Process and outcome in communication of genetic information within families: a systematic review

Attitudes towards disclosure of familial genetic risk in a Mediterranean island population - A survey of the Maltese population

Germline genetic testing has implications that extend beyond the individual patient to relatives, particularly for high-penetrance variants implicated in hereditary cancer or neurodegenerative syndromes. Many countries encourage patient-led communication to inform at-risk relatives, although the efficacy and uptake of this approach varies. Alternative scenarios envisage direct contact mediated by clinicians. The familial disclosure of sensitive genetic information is also determined by complex socio-ethnic factors. To date, no study has explored whether relatives would want to be informed of familial genetic risk and their preferences on different methods of communication in Malta. We thus used a published instrument that utilizes hypothetical scenario methodology to survey the attitudes of the Maltese population (n = 334) to receiving genetic information from family members. Two vignettes on Huntington's disease and colorectal cancer were presented. We also explored preferences towards the communication of genetic risk, confidentiality, and disclosure policies. Our preliminary results show that most respondents want to be informed of their increased risk by a family member or a clinician and would opt to receive confirmatory genetic testing. Most respondents preferred being informed of genetic risk by a close relative, but in the case of non-disclosure would want to be informed by a clinician. Most respondents expressed preference in favour of the introduction of registries, legislative change and sharing of contact details to address cases of nondisclosure. Our findings contribute further to evidence that supports, in selected hypothetical scenarios, an envisioned change in disclosure of genetic data policy by the public that is different from current practice to date.

Testing a Population-Based Outreach Intervention for Ovarian Cancer Survivors to Encourage their Close Relatives to Consider Genetic Counseling

BACKGROUND

Most relatives of women with ovarian cancer are unaware of their increased risk for cancer and their eligibility for genetic counseling. State cancer registries offer a platform to communicate about inherited risk to this population.

METHODS

We conducted a two-arm randomized trial to test a theory-based communication intervention-Your Family Connects (YFC)-compared to the standard Georgia Cancer Registry (GCR) contact. A total of 1,938 eligible ovarian cancer survivors were randomly assigned to either the YFC arm (n = 969) or the Standard Care arm (n = 969). We assessed the number of ovarian cancer survivors and their close relatives who logged on to the study website by arm.

RESULTS

Survivor reach was significantly higher in the Standard Care arm than YFC (20.8% vs. 15.2%, respectively; P < 0.001). However, reach to relatives was limited to listed relatives in the YFC arm (n = 20, 13.2%), with little participation from those in the Standard Care arm (n = 1, 0.4%). Pooling across arms, minority race, longer time since diagnosis, and older age were all significantly associated with a decreased likelihood that the survivor accessed the website.

CONCLUSIONS

The YFC intervention showed lower effectiveness for engaging survivors but was more effective than Standard Care in engaging at-risk relatives. Other factors (e.g., time since diagnosis) associated with lower reach must be considered in refining future outreach approaches.

IMPACT

Partnering with a state cancer registry to foster family communication about inherited cancer risk is feasible but the possibility for broad population reach warrants further testing.

Family Information Management in the Context of Inherited Conditions: An Integrative Review

This review aimed to develop a framework to understand the process of information management in families with inherited conditions. Electronic databases were searched for relevant peer-reviewed articles. Articles were included if they were original research on families affected by any confirmed inherited condition, described how a family accesses, interprets, conveys, and/or uses information about the disease, included the recruitment of more than one family member, and used family as the unit of analysis. Data were analyzed through directed content analysis. Thirty-four articles from 27 studies were analyzed. We propose a framework for family information management consisting of the following domains: contextual influences, family information management behaviors, and family information management outcomes. This proposed framework expands the understanding of how families manage their genetic information in making health care decisions for their affected and at-risk relatives.

Patients' perceptions and practices of informing relatives: a qualitative study within a randomised trial on healthcare-assisted risk disclosure

In a multicentre randomised controlled trial (DIRECT), we evaluate whether an intervention of providing direct letters from healthcare professionals to at-risk relatives (ARRs) affects the proportion of ARRs contacting a cancer genetics clinic, compared with patient-mediated disclosure alone (control). With the aim to explore how the patients included in the trial perceived and performed risk communication with their ARRs we analysed 17 semi-structured interviews with reflexive thematic analysis. All patients described that they disclosed risk information to all close relatives themselves. No integrity-related issues were reported by patients offered the intervention, and all of them accepted direct letters to all their ARRs. Patients' approaches to informing distant relatives were unpredictable and varied from contacting all distant ARRs, sharing the burden with the family, utilising the offer of sending direct letters, vaguely relying on others to inform, or postponing disclosure. Most patients limited their responsibility to the disclosure, although others wanted relatives to get genetic counselling or felt a need to provide additional information to the ARRs before ending their mission. We also identified confusion about the implication of test results, who needed risk information, and who was responsible for informing ARRs. These misunderstandings possibly also affected risk disclosure. This study revealed that despite accepting the direct letters to be sent to all relatives, the patients also contributed to risk disclosure in other ways. It was only in some situations to distant relatives that the healthcare-assisted letter was the only means of communication to the ARRs.

The DCM Project Portal: A direct-to-participant platform of The DCM Research Project

Study objective

To develop a digital platform to conduct family-based, dilated cardiomyopathy (DCM) genetic research.

Design

The DCM Project Portal, a direct-to-participant electronic recruitment, consent, and communication tool, was designed using prior experience with traditional enrollment methods and characteristics and feedback of current participants.

Participants

DCM patients (probands) and their family members enrolled from June 7, 2016 to March 15, 2020 at 25 US advanced heart failure programs.

Results

The portal was designed as a self-guided, three module (registration, eligibility, and consent) process with supporting informational and messaging resources integrated throughout. The experience is tailored to user type and the format adaptable with programmatic growth. Characteristics of participants of the recently completed DCM Precision Medicine Study were assessed as an exemplary user population. A majority of the diverse (34 % non-Hispanic Black (NHE-B), 9.1 % Hispanic; 53.6 % female) proband (n = 1223) and family member (n = 1781) participants aged ≥18 years reported not at all or rarely having problems learning about their health from written information (81 %) and a high confidence in completing medical forms (77.2 % very much or often confident), supporting a self-guided model. A majority of participants across age and race-ethnicity groups reported internet access, with highest rates of no reported access in those ≥77 years (31.9 %), NHE-B (25.2 %), and Hispanic (22.9 %), a similar pattern to those reported by the US Census Bureau as of 2021.

Conclusions

The portal is an example of a digital approach to family-based genetic research that offers opportunity to improve access and efficiency of research operations.

Developing and assessing a kin keeping scale with application to identifying central influencers in African American family networks

Promoting family communication about inherited disease risk is an arena in which family systems theory is highly relevant. One family systems' construct that can support promotion of family communication regarding inherited disease risk is the notion of "kin keeping." However, kin keeping and whether it might be capitalized on to encourage family communication about inherited risk has been understudied. The goal of this report was to propose a broadened conceptualization of kin keeping that distinguishes between a structural functional perspective (role conceptualization) and transitional behaviors (skill conceptualization), and to develop and evaluate a scale that would enable this assertion to be tested among a sample of African American community health workers. We developed a scale using four steps: item development using concept analysis and content validity, scale development among a national sample (n = 312), scale evaluation using exploratory factor analysis (n = 52), and scale reduction. We then posed suppositions of associations that would indicate whether the developed kin keeping measure was assessing a specific family role or set of behaviors. Our results included the development of the first quantitative measure of kin keeping (9- and 15-item scales). Model fit for 9-item scale (CFI = 0.97, AFGI = 0.89, RMSEA = 0.09, SMRM = 0.06) and model fit for 15-item scale (CFI = 0.97, AFGI = 0.89, RMSEA = 0.06, SMRM = 0.05). These findings allow us to move toward more rigorous research about the role of kin keeping on information sharing and health decision making. Results also suggest that, contrary to the historical structural functional conceptualization of kin keeping as a role, kin keeping might also be conceptualized as a behavior or set of modifiable behaviors. Ultimately, the kin keeping scale could be used to operationalize kin keeping in various theoretical models and frameworks, guide intervention development to encourage or train for kin keeping behaviors, and test assumptions of whether families vary in the density of kin keeping.

Clinically Indicated Genomic Sequencing of Children in Foster Care: Legal and Ethical Issues

There are approximately 400 000 children in foster care in the US, approximately one-half of whom have chronic health problems and approximately 10% of whom have complex healthcare needs. Given the increasing relevance of genomic sequencing to guide clinical care for children with rare, chronic, and undiagnosed conditions, it may be an important component of diagnostic evaluation for children in foster care. Clinically indicated genomic sequencing may provide information that has health implications for children in foster care, as well as for their biological parents and other relatives. Whether and how genomic sequencing results impact legal decision making and family court outcomes is not yet well-understood. We describe scenarios that highlight legal, ethical, and policy issues surrounding genomic sequencing for children in foster care using 3 cases adapted from real-world events. Together, these cases highlight important yet underexplored issues that arise when genomic information has legal relevance in family court and ethical implications for child and family well-being. As genomic sequencing becomes more routine for the general pediatric population, additional research is needed to better understand its impacts on children and other stakeholders within the foster care system.

Interventions to support patients with sharing genetic test results with at-risk relatives: a synthesis without meta-analysis (SWiM)

Whilst the finding of heritable susceptibility to disease was once relatively rare, mainstreaming of genetic testing has resulted in a steady increase. Patients are often encouraged to share their genetic test results with relevant relatives, but relatives may not receive this information, leaving them without knowledge of their own risk. Therefore, strategies to help communicate such information are important. This review aimed to explore the efficacy of existing interventions to improve the sharing of genetic test results. A synthesis without meta-analysis design was used. A systematic search of Medline, CINAHL, PsychINFO, and AMED was conducted, and five studies were identified worldwide. Data were extracted for each study regarding study aim, participant characteristics, condition, intervention details, comparison, study duration, outcome measures, theory and behaviour change techniques used. Limited efficacy and application of theory was found. Knowledge, motivation and self-efficacy were not increased in any intervention. No gender differences in communication behaviour were encountered in interventions that recruited men and women. Two studies reported an evaluation of acceptability, which showed that the interventions were well received by patients and health professionals. No study reported the involvement of the target population in any phase of intervention development. Given the lack of health psychology-informed interventions in this area of clinical genetics, we recommend genetic health professionals, health psychologists and patients collaborate on all stages of future interventions that involve the cascading of genetic health information within families. We also provide guidance regarding use of theory and intervention elements for future intervention development.

Your Family Connects: A Theory-Based Intervention to Encourage Communication about Possible Inherited Cancer Risk among Ovarian Cancer Survivors and Close Relatives

INTRODUCTION

Encouraging family communication about possible genetic risk has become among the most important avenues for achieving the full potential of genomic discovery for primary and secondary prevention. Yet, effective family-wide risk communication (i.e., conveying genetic risk status and its meaning for other family members) remains a critical gap in the field. We aim to describe the iterative process of developing a scalable population-based communication outreach intervention, Your Family Connects, to reach ovarian cancer survivors and close relatives to communicate the potential for inherited risk and to consider genetic counseling.

METHODS

Relational-level theories (e.g., interdependence theory) suggest that interventions to promote family cancer risk communication will be most effective if they consider the qualities of specific relationships and activate motives to preserve the relationship. Informed by these theories, we collaborated with 14 citizen scientists (survivors of ovarian cancer or relatives) and collected 261 surveys and 39 structured interviews over 12 weeks of citizen science activities in 2020.

RESULTS

The citizen science findings and consideration of relational-level theories informed the content and implementation of Your Family Connects (www.yourfamilyconnects.org). CS results showed survivors favor personal contact with close relatives, but relatives were open to alternative contact methods, such as through health professionals. Recognizing the need for varied approaches based on relationship dynamics, we implemented a relative contact menu to enable survivors identify at-risk relatives and provide multiple contact options (i.e., survivor contact, health professional contact, and delayed contact). In line with relational autonomy principles, we included pros and cons for each option, assisting survivors in choosing suitable contact methods for each relative.

DISCUSSION

Our developed intervention represents a novel application of relational-level theories and partnership with citizen scientists to expand genetic services reach to increase the likelihood for fair distribution of cancer genomic advances. The Your Family Connects intervention as part of a randomized trial in collaboration with the Georgia Cancer Registry compared with standard outreach.

The DCM Project Portal: A direct-to-participant platform of The DCM Research Project

Study Objective

To develop a digital platform to conduct family-based, dilated cardiomyopathy (DCM) genetic research.

Design

Innovative approaches are needed to achieve large family enrollment targets. The DCM Project Portal, a direct-to-participant electronic recruitment, consent, and communication tool, was designed using prior experience with traditional enrollment methods, characteristics and feedback of current participants, and internet access of the US population.

Participants

DCM patients (probands) and their family members.

Results

The portal was designed as a self-guided, three module (registration, eligibility, and consent) process with internally created supporting informational and messaging resources integrated throughout. The experience can be tailored to user type and the format adapted with programmatic growth. Characteristics of participants of the recently completed DCM Precision Medicine Study were assessed as an exemplary user population. A majority of the diverse (34% non-Hispanic Black (NHE-B), 9.1% Hispanic; 53.6% female) proband (n=1223) and family members (n=1781) participants aged ≥18 years reported not at all or rarely having problems learning about their health from written information (81%) and a high confidence in completing medical forms (77.2% very much or often confident). A majority of participants across age and race-ethnicity groups reported internet access, with highest rates of no reported access in those ≥77 years, NHE-B, and Hispanic, which reflects patterns similar to rates reported by the US Census Bureau as of 2021.

Conclusions

Digital enrollment tools offer opportunity to improve access and efficiency. The portal is an example of a digital approach to family-based genetic research.

Family communication and results disclosure after germline sequencing: A mixed methods study

OBJECTIVE

Research on family communication of germline genome sequencing (GS) results (versus of genetic results after targeted genetic testing) is still emerging, yet potentially complex results increase the importance of communicating risk to relatives. Promoting equity by ensuring patients have sufficient health literacy to interpret results is important in this context. This study aimed to identify cancer patients' perceived importance of result disclosure, predictors of perceptions, and perspectives on family communication.

METHODS

This explanatory-sequential, cross-sectional mixed-methods study involved participants (n = 246) completing a questionnaire and (n = 20) a semi-structured interview. Ordinal logistic regressions determined associations between potential predictors and perceived importance of result disclosure. Interview transcripts were analysed thematically using a constant-comparative approach.

RESULTS

More participants intended disclosing to nuclear (77.4%) than to extended family (42.7%). More than half (59.3%) felt results were family information; 62.7% believed it was important to disclose results to family members. Nuclear and extended family communication scores and education level were significantly positively associated with perceived importance of disclosure (p < 0.05). Six qualitative themes were identified: i) Responsibility to inform, ii) Choice, iii) Autonomy, iv) Family Communication, v) Significance of results, and vi) Health professional role.

CONCLUSION

Low health literacy and family conflict can complicate communication of GS results. Patients seek clear, interpretable information in a format they can easily communicate.

PRACTICE IMPLICATIONS

Healthcare professionals can facilitate discussion of GS results by offering written information, encouraging disclosure, exploring existing family dynamics and communication patterns, and offering strategies to improve family communication. Centralised genetic communication offices and chatbots can also be helpful.

Effectiveness of the Family Heart Talk Communication Tool in Improving Family Member Screening for Dilated Cardiomyopathy: Results of a Randomized Trial

BACKGROUND

Managing disease risk among first-degree relatives of probands diagnosed with a heritable disease is central to precision medicine. A critical component is often clinical screening, which is particularly important for conditions like dilated cardiomyopathy (DCM) that remain asymptomatic until severe disease develops. Nonetheless, probands are frequently ill-equipped to disseminate genetic risk information that motivates at-risk relatives to complete recommended clinical screening. An easily implemented remedy for this key issue has been elusive.

METHODS

The DCM Precision Medicine Study developed Family Heart Talk, a booklet designed to help probands with DCM communicate genetic risk and the need for cardiovascular screening to their relatives. The effectiveness of the Family Heart Talk booklet in increasing cardiovascular clinical screening uptake among first-degree relatives was assessed in a multicenter, open-label, cluster-randomized, controlled trial. The primary outcome measured in eligible first-degree relatives was completion of screening initiated within 12 months after proband enrollment. Because probands randomized to the intervention received the booklet at the enrollment visit, eligible first-degree relatives were limited to those who were alive the day after proband enrollment and not enrolled on the same day as the proband.

RESULTS

Between June 2016 and March 2020, 1241 probands were randomized (1:1) to receive Family Heart Talk (n=621) or not (n=620) within strata defined by site and self-identified race/ethnicity (non-Hispanic Black, non-Hispanic White, or Hispanic). Final analyses included 550 families (n=2230 eligible first-degree relatives) in the Family Heart Talk arm and 561 (n=2416) in the control arm. A higher percentage of eligible first-degree relatives completed screening in the Family Heart Talk arm (19.5% versus 16.0%), and the odds of screening completion among these first-degree relatives were higher in the Family Heart Talk arm after adjustment for proband randomization stratum, sex, and age quartile (odds ratio, 1.30 [1-sided 95% CI, 1.08-∞]). A prespecified subgroup analysis did not find evidence of heterogeneity in the adjusted intervention odds ratio across race/ethnicity strata (P=0.90).

CONCLUSIONS

Family Heart Talk, a booklet that can be provided to patients with DCM by clinicians with minimal additional time investment, was effective in increasing cardiovascular clinical screening among first-degree relatives of these patients.

Evaluating a communication aid for return of genetic results in families with hypertrophic cardiomyopathy: A randomized controlled trial

Genetic testing for hypertrophic cardiomyopathy (HCM) is considered a key aspect of management. Communication of genetic test results to the proband and their family members, can be a barrier to effective uptake. We hypothesized that a communication aid would facilitate effective communication, and sought to evaluate knowledge and communication of HCM risk to at-risk relatives. This was a prospective randomized controlled trial. Consecutive HCM patients attending a specialized clinic, who agreed to participate, were randomized to the intervention or current clinical practice. The intervention consisted of a genetic counselor-led appointment, separate to their clinical cardiology review, and guided by a communication booklet which could be written in and taken home. Current clinical practice was defined as the return of the genetic result by a genetic counselor and cardiologist, often as part of a clinical cardiology review. The primary outcome was the ability and confidence of the individual to communicate genetic results to at-risk relatives. The a priori outcome of improved communication among HCM families did not show statistically significant differences between the control and intervention group, though the majority of probands in the intervention group achieved fair communication (n = 13/22) and had higher genetic knowledge scores than those in the control group (7 ± 3 versus 6 ± 3). A total of 29% of at-risk relatives were not informed of a genetic result in their family. Communication among HCM families remains challenging, with nearly a third of at-risk relatives not informed of a genetic result. We show a significant gap in the current approach to supporting family communication about genetics. Australian New Zealand Clinical Trials Registry: ACTRN12617000706370.

Family Communication about Diagnostic Genetic Testing for Younger-Onset Dementia

Younger-onset dementia (YOD) refers to onset before 65 years of age and may be associated with a genetic cause. Family communication surrounding any genetic risk is complex, and this process may be further complicated in a YOD context due to its effects on cognition, behaviour, and associated psychosocial consequences. This study aimed to investigate how individuals experience family communication about potential genetic risk and testing for YOD. Thematic analysis was performed on verbatim transcripts of nine semi-structured interviews undertaken with family members who attended a neurogenetics clinic due to a relative diagnosed with YOD. The interviews explored the participants’ experiences of learning that YOD might be inherited and the ensuing family communication about genetic testing. Four key themes emerged: (1) a clinical diagnostic odyssey was common and could be a motivator for genomic testing, (2) pre-existing family tension and/or disconnection was a common barrier, (3) family members’ autonomy was considered, and (4) avoidant coping strategies influenced communication. Communication regarding potential YOD genetic risk is a complicated process and may be influenced by pre-existing family dynamics, individual coping mechanisms, and a desire to promote autonomy in relatives. To promote effective risk communication, genetic counsellors should pre-emptively address family tensions that may be exacerbated in the context of genetic testing for YOD, with awareness that family strain during a preceding period of diagnostic odyssey is common. Genetic counsellors can offer psychosocial support to facilitate coping with this tension in an adaptive way. The findings also indicated the importance of extending genetic counselling support to relatives.

Are there differences in perceptions, preferences and attitudes towards disclosure of genetic testing for Stroke? A qualitative study among stroke-free SIREN-SIBS genomics study participants

OBJECTIVE

This study explored perceptions, preferences and attitudes towards disclosure of genetic testing results for stroke among stroke-free controls (and their family members) in the SIREN-SIBS Genomics Study, healthcare providers and policymakers.

MATERIALS AND METHODS

We conducted a qualitative thematic analysis of key informant interviews with 61 participants recruited from community advisory boards (30) and health care providers (31) across seven sites in Nigeria and Ghana.

RESULTS

Major findings illustrate differences in the knowledge of genetic testing with superior knowledge among health care professionals. Relatives and religious leaders were opined as the best to receive the disclosure as they would be able to break the news to the patient in a culturally sensitive manner to reduce the likely resultant emotional outburst. Poor level of awareness of national guidelines for disclosing genetic results exist. Key facilitating factors for disclosure are education, enabling environment, involvement of religious and community leaders, campaigns, and possible treatment options. Disclosure inhibitors include inadequate information, fear of marital break-up or family displacement, fear of stigmatization, fear of isolation, religious beliefs, health worker attitude, and lack of preparedness to accept results.

CONCLUSIONS

These necessitate culturally sensitive interventions for continuing education, increased awareness and sustained engagement to equip all stakeholders in genetic testing disclosure process.

[Management of genetic predisposition to hematologic malignancies in patients undergoing allogeneic hematopoietic cell transplantation (HCT): Guidelines from the SFGM-TC]

The advent of new technologies has made it possible to identify genetic predispositions to myelodysplastic syndromes (MDS) and acute leukemias (AL) more frequently. The most frequent and best characterized at present are mutations in CEBPA, RUNX1, GATA2, ETV6 and DDX41 and, either in the presence of one of these mutations with a high allelic frequency, or in the case of a personal or family history suggestive of blood abnormalities such as non-immune thrombocytopenia, it is recommended to look for the possibility of a hereditary hematological malignancy (HHM). Indeed, early recognition of these HHMs allows better adaptation of the management of patients and their relatives, as allogeneic hematopoietic stem cell transplantation (HSCT) is very often proposed for these pathologies. According to current data, with the exception of the GATA2 mutation, the constitutional or somatic nature of the mutations does not seem to influence the prognosis of hematological diseases. Therefore, the indication for an allograft will be determined according to the usual criteria. However, when searching for a family donor, it is important to ensure that there is no hereditary disease in the donor. In order to guarantee the possibility of performing the HSC allograft within a short period of time, it may be necessary to initiate a parallel procedure to find an unrelated donor. Given the limited information on the modalities of HSC transplantation in this setting, it is important to assess the benefit/risk of the disease and the procedure to decide on the type of conditioning (myeloablative or reduced intensity). In view of the limited experience with the risk of secondary cancers in the medium and long-term, it may be appropriate to recommend reduced intensity conditioning, as in the case of better characterized syndromic hematological diseases such as Fanconi anemia or telomere diseases. In summary, it seems important to evoke HHM more frequently, particularly in the presence of a family history, certain mutations or persistent blood abnormalities, in order to discuss the specific modalities of HSC allografting, particularly with regard to the search for a donor and the evaluation of certain modalities of the procedure, such as conditioning. It should be noted that the discovery of HHM, especially if the indication of an allogeneic HSC transplant is retained, will raise ethical and psychological considerations not only for the patient, but also for his family. A multidisciplinary approach involving molecular biologists, geneticists, hematologists and psychologists is essential.

Human Genetics Society of Australasia Position Statement: Use of Polygenic Scores in Clinical Practice and Population Health

Considerable progress continues to be made with regards to the value and use of disease associated polygenic scores (PGS). PGS aim to capture a person's genetic liability to a condition, disease, or a trait, combining information across many risk variants and incorporating their effect sizes. They are already available for clinicians and consumers to order in Australasia. However, debate is ongoing over the readiness of this information for integration into clinical practice and population health. This position statement provides the viewpoint of the Human Genetics Society of Australasia (HGSA) regarding the clinical application of disease-associated PGS in both individual patients and population health. The statement details how PGS are calculated, highlights their breadth of possible application, and examines their current challenges and limitations. We consider fundamental lessons from Mendelian genetics and their continuing relevance to PGS, while also acknowledging the distinct elements of PGS. Use of PGS in practice should be evidence based, and the evidence for the associated benefit, while rapidly emerging, remains limited. Given that clinicians and consumers can already order PGS, their current limitations and key issues warrant consideration. PGS can be developed for most complex conditions and traits and can be used across multiple clinical settings and for population health. The HGSA's view is that further evaluation, including regulatory, implementation and health system evaluation are required before PGS can be routinely implemented in the Australasian healthcare system.

Dilemmas when talking about Huntington's disease: A qualitative study of offspring and caregiver experiences in Norway

Research provides a compelling list of reasons why offspring should be included in honest conversations about disease when the disease affects their caregivers. Despite this, we lack in-depth knowledge about how families affected by the severe and complex genetic condition Huntington's disease (HD) experience talking about the many aspects of how this disease affects their lives. This study aimed to provide an in-depth exploration of how offspring with a caregiver with HD and caregivers with a partner with HD experienced talking about disease throughout childhood. Thematic analysis was conducted with semistructured interviews of both caregivers (n = 14) and offspring (n = 36) from families affected by HD, reflecting both current and past experiences. In addition to highlighting the many needs offspring have for knowledge and conversation about the disease with their caregivers, our findings also show that a variety of dilemmas can follow these conversations, including when to talk, what to say, how often HD should be talked about on a day-to-day basis, and whether to share disease-related information with others outside the family. The findings show the complexity of talking with offspring about HD. A difficult task for both offspring and caregivers seemed to be finding out how to balance the many dilemmas that arise in conversations and how to use dialogue to best help offspring adapt and cope with the many challenges that can come with HD. The findings can assist health care professionals, such as genetic counselors, prepare, and guide families affected by HD in the many and complex conversations that arise about the disease, in turn helping offspring adjust and cope with their current lives or future lives affected by HD.

From the patient to the population: Use of genomics for population screening

Genomic medicine is expanding from a focus on diagnosis at the patient level to prevention at the population level given the ongoing under-ascertainment of high-risk and actionable genetic conditions using current strategies, particularly hereditary breast and ovarian cancer (HBOC), Lynch Syndrome (LS) and familial hypercholesterolemia (FH). The availability of large-scale next-generation sequencing strategies and preventive options for these conditions makes it increasingly feasible to screen pre-symptomatic individuals through public health-based approaches, rather than restricting testing to high-risk groups. This raises anew, and with urgency, questions about the limits of screening as well as the moral authority and capacity to screen for genetic conditions at a population level. We aimed to answer some of these critical questions by using the WHO Wilson and Jungner criteria to guide a synthesis of current evidence on population genomic screening for HBOC, LS, and FH.

Extended family outreach in hereditary cancer using online genealogy, direct-to-consumer ancestry genetics, and social media: A mixed methods process evaluation of the ConnectMyVariant intervention (Preprint)

BACKGROUND

Cascade screening, defined as helping at-risk relatives get targeted genetic testing of familial variants for dominant hereditary cancer syndromes, is a proven component of cancer prevention; however, its uptake is low. We developed and conducted a pilot study of the ConnectMyVariant intervention, in which participants received support to contact at-risk relatives that extended beyond first-degree relatives and encourage relatives to obtain genetic testing and connect with others having the same variant through email and social media. The support that participants received included listening to participants' needs, assisting with documentary genealogy to find common ancestors, facilitating direct-to-consumer DNA testing and interpretation, and assisting with database searches.

OBJECTIVE

We aimed to assess intervention feasibility, motivations for participating, and engagement among ConnectMyVariant participants and their families.

METHODS

We used a mixed methods design including both quantitative and qualitative evaluation methods. First, we considered intervention feasibility by characterizing recruitment and retention using multiple recruitment mechanisms, including web-based advertising, dissemination of invitations with positive test results, provider recruitment, snowball sampling, and recruitment through web-based social networks and research studies. Second, we characterized participants' motivations, concerns, and engagement through project documentation of participant engagement in outreach activities and qualitative analysis of participant communications. We used an inductive qualitative data analysis approach to analyze emails, free-text notes, and other communications generated with participants as part of the ConnectMyVariant intervention.

RESULTS

We identified 84 prospective participants using different recruitment mechanisms; 57 participants were ultimately enrolled in the study for varying lengths of time. With respect to motivations for engaging in the intervention, participants were most interested in activities relating to genealogy and communication with others who had their specific variants. Although there was a desire to find others with the same variant and prevent cancer, more participants expressed an interest in learning about their genealogy and family health history, with prevention in relatives considered a natural side effect of outreach. Concerns about participation included whether relatives would be open to communication, how to go about it, and whether others with a specific variant would be motivated to help find common ancestors. We observed that ConnectMyVariant participants engaged in 6 primary activities to identify and communicate with at-risk relatives: sharing family history, family member testing, direct-to-consumer genealogy genetic testing analysis, contacting (distant) relatives, documentary genealogy, and expanding variant groups or outreach. Participants who connected with others who had the same variant were more likely to engage with several extended family outreach activities.

CONCLUSIONS

This study demonstrated that there is an interest in extended family outreach as a mechanism to improve cascade screening for hereditary cancer prevention. Additional research to systematically evaluate the outcomes of such outreach may be challenging but is warranted.

Understanding the Patient Experience of Receiving Clinically Actionable Genetic Results from the MyCode Community Health Initiative, a Population-Based Genomic Screening Initiative

Understanding unselected individuals’ experiences receiving genetic results through population genomic screening is critical to advancing clinical utility and improving population health. We conducted qualitative interviews with individuals who received clinically actionable genetic results via the MyCode© Genomic Screening and Counseling program. We purposively sampled cohorts to seek diversity in result-related disease risk (e.g., cancer or cardiovascular) and in personal or family history of related diseases. Transcripts were analyzed using a two-step inductive coding process of broad thematic analysis followed by in-depth coding of each theme. Four thematic domains identified across all cohorts were examined: process assessment, psychosocial response, behavioral change due to the genetic result, and family communication. Coding of 63 interviews among 60 participants revealed that participants were satisfied with the results disclosure process, initially experienced a range of positive, neutral, and negative psychological reactions to results, adjusted positively to results over time, undertook clinically indicated actions in response to results, and communicated results with relatives to whom they felt emotionally close. Our findings of generally favorable responses to receiving clinically actionable genetic results via a genomic screening program may assuage fear of patient distress in such programs and guide additional biobanks, genomic screening programs, and research studies.

Survey on experiences and attitudes of parents toward disclosing information to children with genetic syndromes and their siblings in Japan

Many parents face the dilemma of when, how, and what to disclose to their children regarding their genetic conditions. The purpose of this study was to learn about the experiences of parents regarding disclosing information to their children with genetic conditions. A questionnaire was sent to 378 parents of children and adolescents with the following genetic syndromes: 22q11.2 deletion syndrome, Beckwith-Wiedemann syndrome, Noonan syndrome, Russell-Silver syndrome, Kabuki syndrome, Williams syndrome, Prader-Willi syndrome, and Sotos syndrome. Findings were analyzed using descriptive statistics for multiple-choice questions. Of the parents surveyed, 158 (41.8%) responded to the questionnaires. The average age of children with genetic syndromes was 12 years. Sixty-seven parents had disclosed relevant information to their children, whereas 91 had not. Among them (who had disclosed information), out of 53 respondents who answered that their affected child had siblings, 50 had disclosed the genetic condition of the affected child to the siblings as well. Sixty-eight out of 91 respondents who had not told information to affected child were planning to disclose the information in the future. Many respondents who had disclosed information did not regret this. They felt good talking about genetic conditions, and had talked about genetic conditions with the affected children following disclosure. This study contributed to our understanding of the attitudes of parents towards disclosing information to children with genetic syndromes.

A systematic review of theory-informed strategies used in interventions fostering family genetic risk communication

BACKGROUND

Inherited risk is a family issue. Identifying family members who carry a pathogenic genetic variant that increases risk of cancers and other chronic diseases can be lifesaving for those affected.

OBJECTIVE

The research questions are: (1) which family communication frameworks have been applied, (2) how do intervention strategies employed map to these theories, and (3) to what extent were families receptive to these strategies and communication increased?

METHODS

Manuscripts published between January 2010 and August 2020 were searched in three databases: PubMed, PsycINFO, and Web of Science.

RESULTS

Nine intervention trials were identified. All interventions were evaluated in clinical genetic counseling contexts using at least one individual-level strategy (e.g. increase knowledge). Only three focused on dyadic conversations such as preparing for relatives' information needs.

CONCLUSIONS

This systematic review posed the question whether theoretically based approaches have been applied to foster family genetic risk communication. Greater attention needs to be paid to the utilization of dyadic level and family system level theories to guide intervention developments.

PRACTICAL IMPLICATIONS

We conclude by calling for accelerating and broadening the development of interventions to enable family communication about inherited risk that are theory-based, incorporate family-systems thinking, and are conducted outside of specialty clinic settings.

The Impact of Proband Indication for Genetic Testing on the Uptake of Cascade Testing Among Relatives

Although multiple factors can influence the uptake of cascade genetic testing, the impact of proband indication has not been studied. We performed a retrospective, cross-sectional study comparing cascade genetic testing rates among relatives of probands who received either diagnostic germline testing or non-indication-based proactive screening via next-generation sequencing (NGS)-based multigene panels for hereditary cancer syndromes (HCS) and/or familial hypercholesterolemia (FH). The proportion of probands with a medically actionable (positive) finding were calculated based on genes associated with Centers for Disease Control and Prevention (CDC) Tier 1 conditions, HCS genes, and FH genes. Among probands with a positive finding, cascade testing rates and influencing factors were assessed. A total of 270,715 probands were eligible for inclusion in the study (diagnostic n = 254,281,93.9%; proactive n = 16,434, 6.1%). A positive result in a gene associated with a CDC Tier 1 condition was identified in 10,520 diagnostic probands (4.1%) and 337 proactive probands (2.1%), leading to cascade testing among families of 3,305 diagnostic probands (31.4%) and 36 proactive probands (10.7%) (p < 0.0001). A positive result in an HCS gene was returned to 23,272 diagnostic probands (9.4%) and 970 proactive probands (6.1%), leading to cascade testing among families of 6,611 diagnostic probands (28.4%) and 89 proactive probands (9.2%) (p < 0.0001). Cascade testing due to a positive result in an HCS gene was more commonly pursued when the diagnostic proband was White, had a finding in a gene associated with a CDC Tier 1 condition, or had a personal history of cancer, or when the proactive proband was female. A positive result in an FH gene was returned to 1,647 diagnostic probands (25.3%) and 67 proactive probands (0.62%), leading to cascade testing among families of 360 diagnostic probands (21.9%) and 4 proactive probands (6.0%) (p < 0.01). Consistently higher rates of cascade testing among families of diagnostic probands may be due to a perceived urgency because of personal or family history of disease. Due to the proven clinical benefit of cascade testing, further research on obstacles to systematic implementation and uptake of testing for relatives of any proband with a medically actionable variant is warranted.

Communal Coping as a Strategy to Enhance Family Engagement in Dilated Cardiomyopathy

Background:

Assuring that relatives are informed about a genetic diagnosis and have appropriate medical follow-up can be challenging. We hypothesize that communal coping (CC)—an approach in which a group views a stressor (such as a new genetic diagnosis) as our problem, versus my or your problem, and takes joint action to address it—can help families to address this challenge. A better understanding of CC could also inform counseling interventions to promote CC and family follow-up.

Methods:

In the Dilated Cardiomyopathy (DCM) PM study (Precision Medicine), living first-degree relatives of DCM probands were invited to undergo clinical screening; 31% of these did so. This research program offers the opportunity to determine the frequency of CC in DCM families, assess whether CC attitudes and actions occurred more commonly among families in which family members participated, and conduct prospective follow-up to evaluate family coping and counseling needs over time.

Results:

The proposed studies will provide evidence about the frequency of CC attitudes and actions among DCM families, assess the association of CC with increased family follow-up, and identify counseling needs related to family follow-up.

Conclusions:

The DCM PM study offers an opportunity to test the hypothesis that CC contributes to increased family follow-up and generate evidence to inform counseling interventions to encourage such follow-up.

Application of motivational interviewing strategies with the extended parallel process model to improve risk communication for parents of children with familial hypercholesterolemia

Current genetic counseling practice has not been found to significantly increase risk communication between family members. A more diverse set of genetic counseling approaches may be needed. A genetic counseling intervention based on motivational interviewing principles and the extended parallel process model was utilized to increase cascade outcomes within families with familial hypercholesterolemia, a common, underdiagnosed, and treatable condition. Parents of children with familial hypercholesterolemia were invited to participate in an online pre-survey, single-session genetic counseling intervention, and post-intervention surveys as a part of the CHEERS (Cholesterol Evaluation to Explore Risk Screening) intervention. This study investigated the efficacy of a genetic counselor delivered motivational interviewing intervention and how parents of children with familial hypercholesterolemia react by assessing family member cholesterol screening and risk communication to at-risk relatives. Transcripts were audio-recorded, transcribed, and analyzed for change talk using the Motivational Interviewing Skill Code version 2.1. Participant surveys were analyzed for self-reported extended parallel process constructs and motivations. Coincidence analysis was conducted to explore differences between those with and without positive cascade outcomes within 12 months after the intervention. On average, change talk increased during the session in order of the extended parallel process constructs (perceived severity, susceptibility, response efficacy, self-efficacy). Coincidence analysis revealed that 6 of the 7 cases with positive cascade outcomes were explained by either the presence of high change talk during the intervention or presence of positive motivations shortly after, while 5 of the 5 cases without a positive outcome lacked both of these key factors that were associated with cascade outcomes. Results of this study suggest that incorporating motivational interviewing and the extended parallel process model increases change talk and that the presence of either high levels of change talk or positive motivations is associated with positive cascade outcomes.

Effectively communicating comprehensive tumor genomic profiling results: Mitigating uncertainty for advanced cancer patients

OBJECTIVE

To understand advanced cancer patients' experience of uncertainty when receiving comprehensive tumor genomic profiling (CTGP) results, and their perceptions of how healthcare provider (HCP) communication impacts uncertainty.

METHODS

Thirty-seven semi-structured interviews with advanced cancer patients were conducted within two weeks of patients receiving CTGP results. Transcripts were thematically analyzed, using an inductive approach.

RESULTS

We identified three themes that illustrate patient experience of uncertainties when receiving CTGP results: 1. Type and degree of uncertainty fluctuates along with changing illness circumstances and the nature of the CTGP results; 2. HCPs' co-ordination of care and communication shapes uncertainty, with immediate, clearer and simpler information promoting certainty; and 3. Patients felt that communicating results to reduce relatives' uncertainty is important, with patients choosing the time and process for achieving this and desiring HCPs support.

CONCLUSION

Oncology patients are confronted with an array of uncertainties. Clear, simple communication from HCPs about results and their implications, and support to manage uncertainty, will be of benefit.

PRACTICE IMPLICATIONS

If CTGP is to become routine clinical practice, clear communication will be crucial in reducing uncertainty. Awareness of potential uncertainties experienced by patients when receiving results, will assist HCPs to address uncertainties, reduce uncertainty where possible, and offer targeted support to patients struggling with uncertainty.

La médecine prédictive à l’épreuve de l’oncohématologie : réflexions à partir de la clinique

Le développement de l’oncogénétique permet de mieux adapter le traitement pour les patients atteints de cancer et aussi de proposer, dans les cas d’anomalies génétiques héréditaires, un suivi adapté aux proches concernés. Néanmoins, les nouvelles technologies de séquençage suscitent des questions éthiques et cliniques, notamment quant à l’impact psychologique de ces tests génétiques. Nous abordons la spécificité de l’identification de mutations génétiques constitutionnelles dans le cadre de l’oncohématologie.

Patient-reported anticipated barriers and benefits to sharing cancer genetic risk information with family members

While prior studies have largely focused on family communication of diagnostic single-gene test results or specific types of cancer testing results, far less work has investigated family communication of cancer-related genetic results that include multi-gene panels, a broad array of cancer types/stages, and participants without family history of cancer. The study we report here examined individuals' anticipated barriers and benefits to sharing genetic information with family members. An 80+ gene panel was performed on participants recruited from Mayo Clinic, diagnosed with different cancer types, who did not have a family history suggestive of an inherited risk. Participants completed a 49-item survey before receiving genetic test results. Family variant testing was provided to family members at no cost, allowing factors influencing intent to share to be examined in the absence of financial burdens. In all, 1721 of 2984 individuals who received genetic testing completed the survey (57.7% completion rate). Participants' intent to share with parents, siblings, and children was inversely related to the number of anticipated barriers to sharing and directly related to the number of anticipated benefits to sharing. Of those participants who did not intend to share with parents, siblings, and adult children, 64.8%, 30.3%, and 67.6% reported that there were no barriers, while 17.1%, 24.5%, and 40.2.% reported there were no benefits. Findings indicate that barriers to sharing genetic information with family members vary across family member types, and an inability to identify at least one benefit of sharing with family members is a predictor of intent not to share.

A Focus Group Study of Perceptions of Genetic Risk Disclosure in Members of the Public in Sweden: "I'll Phone the Five Closest Ones, but What Happens to the Other Ten?"

This study explores perceptions and preferences on receiving genetic risk information about hereditary cancer risk in members of the Swedish public. We conducted qualitative content analysis of five focus group discussions with participants (n = 18) aged between 24 and 71 years, recruited from various social contexts. Two prominent phenomena surfaced around the interplay between the three stakeholders involved in risk disclosure: the individual, healthcare, and the relative at risk. First, there is a genuine will to share risk information that can benefit others, even if this is difficult and causes discomfort. Second, when the duty to inform becomes overwhelming, compromises are made, such as limiting one’s own responsibility of disclosure or projecting the main responsibility onto another party. In conclusion, our results reveal a discrepancy between public expectations and the actual services offered by clinical genetics. These expectations paired with desire for a more personalized process and shared decision-making highlight a missing link in today’s risk communication and suggest a need for developed clinical routines with stronger healthcare–patient collaboration. Future research needs to investigate the views of genetic professionals on how to address these expectations to co-create a transparent risk disclosure process which can realize the full potential of personalized prevention.

Family Communication Patterns and Challenges of Huntington's Disease Risk, the Decision to Pursue Presymptomatic Testing, and Test Results

BACKGROUND

Communicating genetic information within families can provide individuals with the emotional support, alert family members to their own potential risk, and strengthen relationships. However, these communications have the potential to cause emotional distress to individuals and family members if family members are informed of a risk they do not wish to know or discuss. Communication about the decision to pursue testing and test results are especially sensitive in Huntington's disease (HD), where individuals often feel strongly about either knowing or not knowing their genetic status.

OBJECTIVE

To examine family communication patterns of genetic risk, the decision to pursue testing, and test results not just years, but decades after testing for HD, and examine how family communication of genetic risk information affects family relationships over the long-term.

METHODS

In this qualitative study, 39 semi-structured interviews were conducted with probands who went through genetic testing for HD. Clinic notes from these individuals were also analyzed.

RESULTS

Family communication patterns varied based on relation (e.g., significant others, child, extended family) and were influenced by a variety of factors. Sharing with spouses and children had a positive influence on the relationship in most cases. Sharing with extended family members had varying effects on relationships. Negative effects were more likely when family members were in denial, had not pursued testing for themselves, or did not support testing.

CONCLUSION

Communication to significant others and children, should be discussed with and supported in individuals seeking testing for HD, but for extended family members, potential effects on the relationship, emotional distress, and benefits should be discussed and weighed.

Relationship between genetic knowledge and familial communication of CRC risk and intent to communicate CRCP genetic information: insights from FamilyTalk eMERGE III

Successful translation of genetic information into patient-centered care and improved outcomes depends, at least in part, on patients' genetic knowledge. Although genetic knowledge is believed to be an important facilitator of familial communication of genetic risk information, empirical evidence of this association is lacking. We examined whether genetic knowledge was related to frequency of current familial communication about colorectal cancer and polyp (CRCP) risk, and future intention to share CRCP-related genomic test results with family members in a clinical sample of patients. We recruited 189 patients eligible for clinical CRCP sequencing to the eMERGE III FamilyTalk randomized controlled trial and surveyed them about genetic knowledge and familial communication at baseline. Participants were primarily Caucasian, 47% male, average age of 68 years, mostly well educated, and with high-income levels. Genetic knowledge was positively associated with future-intended familial communication of genetic information (odds ratio = 1.11, 95% confidence interval: 1.02-1.23), but not associated with current communication of CRC risk (β = 0.01, p = .58). Greater current communication of CRC risk was associated with better family functioning (β = 0.04, p = 8.2e-5). Participants' genetic knowledge in this study was minimally associated with their intended familial communication of genetic information. Although participants have good intentions of communication, family-level factors may hinder actual follow through of these intentions. Continued focus on improving proband's genetic knowledge coupled with interventions to overcome family-level barriers to communication may be needed to improve familial communication rates.

"Let's Talk about Skin Cancer": Examining Association between Family Communication about Skin Cancer, Perceived Risk, and Sun Protection Behaviors

Family communication about skin cancer risk may motivate protective behaviors. However, it is unclear how widespread such communication might be. In this study, we describe prevalence and patterns (across environmental, personal, and behavioral factors) of family communication about skin cancer across N = 600 diverse (79% female, 48% Hispanic, 44% non-Hispanic White) primary care patients from Albuquerque, New Mexico, a geographical location with year-round sun exposure. Over half reported discussing general cancer (77%) and skin cancer risks (66%) with their families. The most frequent target of skin cancer risk communication included doctors (54%), followed by friends/coworkers (49%), spouse/partner (43%), other family members (38%), sisters (36%), mothers (36%), daughters (33%), sons (32%), father (24%), and brothers (22%). On average, participants reported having talked to three family members about skin cancer risks. The most frequently discussed content of skin cancer risk communication was the use of sun protection (89%), followed by the personal risk of skin cancer (68%), who had skin cancer in the family (60%), family risk of skin cancer (59%), time of sun exposure (57%), and skin cancer screening (57%). A family or personal history of cancer, higher perceived risk, higher health literacy, being non-Hispanic, having higher education or income, and proactive sun protective behavior were associated with greater family communication about general cancer and skin cancer risks. These study findings have implications for interventions that encourage discussions about skin cancer risk, sun protection, and skin cancer screening that lead to adoption of sun-safe behaviors.

Factors that Influence Intent to Share Genetic Information Related to Cancer Risk with Family Members

We describe factors influencing patient decisions to share positive cancer genetic test results with family members. We focused on patients who were diagnosed with several different cancer types but did not have a family history that was suggestive of an inherited risk. Participants were recruited from Mayo Clinic and had been recently diagnosed with cancer. An 80+ gene panel was performed. Before receiving genetic test results, patients completed a 49-item survey on their intent to share their results with relatives. 1,721 (57.7%) of 2,984 individuals who elected to pursue genetic testing completed the survey. Most patients planned to share cancer-related genetic results with a spouse or partner (97.0%), at least one adult child (92.2%), at least one sibling (86.2%), and with at least one parent (70.3%). Familial support scores and familial communication scores were predictive of intent to share cancer-related genetic test results. Our data highlight differences in family communication capacity and support that are important for clinicians to consider when supporting patients who wish to share cancer-related genetic test results with family members. Our data point to several potential interventional strategies that might increase the likelihood of cancer-related genetic test results being shared with family members at risk.

Cascade screening for beta-thalassemia in Pakistan: development, feasibility and acceptability of a decision support intervention for relatives

The government-funded ‘Punjab Thalassaemia Prevention Project’ (PTPP) in Pakistan includes cascade screening for biological relatives of children with beta-Thalassaemia Major (β-TM). However, there is low uptake of cascade screening. This paper presents the (i) development of a paper-based ‘decision support intervention for relatives’ (DeSIRe) to enable PTPP Field Officers to facilitate informed decision making about carrier testing, and (ii) assessment of the feasibility and acceptability of the DeSIRe. The intervention was developed using the International Patient Decision Aids Standards quality criteria and Ottawa Decision Support Framework. Twelve focus groups were conducted (September and October 2020) to explore the views of healthcare professionals (HCPs) and relatives of children with β-TM, in six cities. The focus groups were attended by 117 participants (60 HCPs and 57 relatives). Thematic analysis showed that the DeSIRe was considered acceptable for supporting relatives to make informed decisions about cascade screening, and potentially feasible for use in clinical practice. Suggestions for changing some words, the structure and adding information about how carrier testing relates to consanguineous marriages will enable further development of the DeSIRe. Participants generally welcomed the DeSIRe; however, they highlighted the perceived need to use more directive language, hence showed a cultural preference for directive genetic counselling. The findings highlight challenges for researchers using western theories, frameworks, policies and clinical guidelines to develop decision support interventions for implementation more globally. Future research is needed to evaluate the use of the DeSIRe in routine practice and whether it enables relatives to make informed decisions.

Development of a Secure Website to Facilitate Information Sharing in Families at High Risk of Bowel Cancer-The Familyweb Study

Simple Summary

Families with an inherited high risk of bowel cancer may struggle to share information about their diagnosis. This means that relatives are not always aware of their increased risk of cancer or able to access screening for the early detection of cancer. Through this study, we aimed to help such families by creating a website where patients could share confidential information with their relatives securely online. Following a survey and telephone interviews with affected individuals, the content of the website was developed to suit the needs of families. Website function was tested with patients to check feasibility and acceptability. Most participants wanted more information to support their adaptation to the diagnosis and help inform their relatives. This study demonstrates how health professionals can improve access to genetic testing and cancer screening in families at high risk of cancer, thus reducing morbidity and mortality.

Abstract

Individuals with pathogenic variants in genes predisposing to bowel cancer are encouraged to share this information within their families. Close relatives at 50% risk can have access to bowel cancer surveillance. However, many relatives remain unaware of their vulnerability or have insufficient information. We investigated the feasibility and acceptability of using a secure website to support information sharing within families at high risk of bowel cancer. Patients (n = 286) answered an anonymous cross-sectional survey, with 14 participating in telephone interviews. They reported that the diagnosis had a profound effect on them and their family relationships, and consequently desired more support from health professionals. Website content was created in response to the preferences of survey and interview participants. Reactions to the website from 12 volunteers were captured through remote usability testing to guide further refinement of the website. Participants welcomed the opportunity to store and share personal information via the website and wanted more information and help informing their relatives about the diagnosis. Important website topics were: healthy lifestyle; genetic testing; and how to talk to children about the diagnosis. A website providing online access to confidential documents was both feasible and acceptable and could translate into increased uptake of cancer surveillance, resulting in lower morbidity and mortality in these families.

Family communication about genomic sequencing: A qualitative study with cancer patients and relatives

OBJECTIVE

This study explored family communication about undertaking genomic sequencing, and intentions to communicate pertinent heritable results to family members.

METHODS

Semi-structured interviews were conducted with cancer patients (n = 53) and their relatives (n = 20) who underwent germline genome sequencing or molecular tumor testing. Interviews were audio-recorded, transcribed and analyzed using thematic analysis.

RESULTS

Key themes relevant to family communication about undertaking sequencing included: perceiving family member interest, delaying discussion until results were received, having shared capacity to understand and cope, and having open communication in the family. Intended communication subsequent to receiving results was affected by: disease severity, risk management options, degree of closeness in the family, sense of responsibility, and potential adverse impacts on family. Resource and support needs varied based on the complexity of test results, health professionals' availability, and disease severity. Unique subthemes were identified for specific subgroups.

CONCLUSION

Current findings support the need to assess the impact and resource needs specific to each clinical application of genomic sequencing.

PRACTICE IMPLICATIONS

Increasingly sophisticated and complex clinical genomic sequencing warrants development of family-centered interventions and resources to facilitate preference-sensitive communication about genomic sequencing, including disseminating relevant information to family members.

Usefulness of mobile apps for communication of genetic test results to at-risk family members in a U.S. integrated health system: a qualitative approach from user-testing

Objective

To assess the usefulness a mobile based application to send genetic test results to at-risk family members in a U.S. integrated health system.

Methods

We conducted semi-structured in-person interviews with members of Kaiser Permanente Washington who had enrolled in a prospective study and received genetic test results. Participants were given the task to use the app and comment on the experience. The moderator asked participants to share perspectives on the usefulness of a mobile based app and their lived experiences of sharing their test results with family members.

Results

Fourteen study participants who had undergone genetic testing were interviewed. Four primary themes emerged as relevant to the use of mobile-based apps as a tool for communicating genetic test results to at-risk family members: (i) Participants felt a sense of obligation to share positive test results with relatives; (ii) Participants felt that the advantages of using email were similar to those of the app; (iii) Participants felt that younger individuals would be more comfortable with an app; and, (iv) Participants felt they could use the app independently and in their own time.

Conclusion

A mobile based app could be used as a tool to improve cascade screening for pathogenic/likely pathogenic test results. The benefits of such a tool are likely greatest among relatives still at the stage of family planning, as well as among family members with strained relationships. There would be minimal burden on the system to offer a mobile based app as a tool.

Disclosure of familial implications of pathogenic variants in breast-cancer genes to patients: Opportunity for prompting family communication

Familial communication of pathogenic genetic variants is necessary to maximize the clinical utility of genetic testing and its public health benefits. Insights to family communication considerations may be obtained from existing clinical documentation available in medical records. The goal of this study was to describe and characterize information about family communication of pathogenic variants and cascade genetic testing from genetic counseling summary notes. We completed structured content analysis of 656 summary notes describing pathogenic variants in breast cancer genes, for patients seen at a tertiary cancer center. Patients were 89.5% female, median age of 49 years, 32.6% non-White, and were counseled by 23 unique genetic counselors (GCs) with mean post-certification experience of 3.7 years. Cascade genetic testing was documented in 92.2% of all notes. Specific relatives (i.e., relationship to patient) who would benefit from genetic counseling and cascade testing were referenced in 33.1% of notes. Specific risk messaging was 2.5 times more likely to be present in notes of high- compared to moderate-risk genes (OR=2.53, 95% CI: 1.71-3.80), and when summary notes indicated the presence of a friend or relative (OR=2.29, 95% CI: 1.50-3.48). Summary notes frequently attempted to contextualize the patients' familial relationships by referencing positive family communication patterns (41.6%) or negative communication issues (2.4%) and included various strategies to address barriers to communication and assist relatives with cascade testing. Overall, GCs consistently documented family communication recommendations when pathogenic variants are identified on patients' genetic testing, albeit with heterogeneous use of specific communication prompts.

A family systems approach to genetic counseling: Development of narrative interventions

To what extent are family systems approaches relevant in the genomics era? What difference does it make to remember the wider social context within which ‘problems’ associated with a genetic diagnosis reside? How does this influence the conversations we have with our patients? These questions will be considered in relation to systemic approaches to genetic counseling practice. Narrative therapy with an emphasis on people's strengths, wishes, and ways of resisting the effects of a problem may be a particularly useful framework for genetic counselors. Narrative practice views people as multi‐storied and is concerned with the question of how we encourage people to tell their stories in ways that make them feel stronger. Increased uptake of genomic testing and the number of people seeking genetic counseling present opportunities to consider new ways of working, particularly around support following a new genetic diagnosis. One option is to realize the potential of group interventions. Family therapy and narrative practices have the potential to encourage communication and for families to learn from each other.

Misinterpretation of Hereditary Breast Cancer Risk and Its Association with Information Sharing Motives among Women at Low Likelihood of Carrying a BRCA1/2 Mutation

PURPOSE

In this brief report, we ask whether women's interpretation of breast cancer risk based on their low likelihood of carrying a BRCA1/2 mutation is associated with their information-sharing behavior, and whether misinterpretation is associated with motives for sharing the result.

METHODS

Women in mammography clinics who completed a brief family history assessment and deemed to be at low likelihood of carrying a BRCA1/2 mutation were asked to complete a 1-time online survey between June 2016 and January 2017.

RESULTS

One-third (44/148) of women shared their family history screen result with someone in their social network. Result information was shared largely with a first-degree female relative to express feelings of relief (77%, 33/43). There were no differences in likelihood of sharing based on breast cancer risk interpretation. However, women who misinterpreted the implications of the result for general breast cancer risk reported more motives to share the result with their social network than those who accurately interpreted their breast cancer risk.

CONCLUSIONS

As family history-based screening for hereditary breast cancer is broadly implemented, the communication needs of the majority of women who will be unlikely of carrying a BRCA1/2 mutation must be considered. The motives of women who misinterpreted the implications of this result for breast cancer risk suggest the possibility that miscommunication could be spread to the broader family network.

Public support for healthcare-mediated disclosure of hereditary cancer risk information: Results from a population-based survey in Sweden

Background

Targeted surveillance of at-risk individuals in families with increased risk of hereditary cancer is an effective prevention strategy if relatives are identified, informed and enrolled in screening programs. Despite the potential benefits, many eligible at-risk relatives remain uninformed of their cancer risk. This study describes the general public's opinion on disclosure of hereditary colorectal cancer (CRC) risk information, as well as preferences on the source and the mode of information.

Methods

A random sample of the general public was assessed through a Swedish citizen web-panel. Respondents were presented with scenarios of being an at-risk relative in a family that had an estimated increased hereditary risk of CRC; either 10% (moderate) or 70% (high) lifetime risk. A colonoscopy was presented as a preventive measure. Results were analysed to identify significant differences between groups using the Pearson's chi-square (χ²) test.

Results

Of 1800 invited participants, 977 completed the survey (54%). In the moderate and high-risk scenarios, 89.2 and 90.6% respectively, would like to receive information about a potential hereditary risk of CRC (χ2, p = .755). The desire to be informed was higher among women (91.5%) than men (87.0%, χ2, p = .044). No significant differences were found when comparing different age groups, educational levels, place of residence and having children or not. The preferred source of risk information was a healthcare professional in both moderate and high-risk scenarios (80.1 and 75.5%). However, 18.1 and 20.1% respectively would prefer to be informed by a family member. Assuming that healthcare professionals disclosed the information, the favoured mode of information was letter and phone (38.4 and 33.2%).

Conclusions

In this study a majority of respondents wanted to be informed about a potential hereditary risk of CRC and preferred healthcare professionals to communicate this information. The two presented levels of CRC lifetime risk did not significantly affect the interest in being informed. Our data offer insights into the needs and preferences of the Swedish population, providing a rationale for developing complementary healthcare-assisted communication pathways to realise the full potential of targeted prevention of hereditary CRC.

What Is the Psychosocial Impact of Providing Genetic and Genomic Health Information to Individuals? An Overview of Systematic Reviews

Optimistic predictions that genetic and genomic testing will provide health benefits have been tempered by the concern that individuals who receive their results may experience negative psychosocial outcomes. This potential ethical and clinical concern has prompted extensive conversations between policy-makers, health researchers, ethicists, and the general public. Fortunately, the psychosocial consequences of such testing are subject to empirical investigation, and over the past quarter century, research that clarifies some of the types, likelihood, and severity of potential harms from learning the results of the testing has accumulated. I aim to provide an overview of the findings of this research by looking at selected systematic reviews. This will convey the gist of the literature's quality and coverage, reveal gaps in existing knowledge, and highlight promising areas for future scholarship.

From Probands to Relatives: Communication of Genetic Risk for Hereditary Breast-Ovarian Cancer and Its Influence on Subsequent Testing

BACKGROUND

The genetic risk communication from proband to relatives varies from family to family, and patients often need support with the communication of genetic test results and making decisions to manage hereditary cancer risks.

OBJECTIVE

The aim of this study was to characterize the communication of BRCA1 or BRCA2 (BRCA1/2) genetic risk from proband to first-degree relatives (FDRs) using a social network framework.

METHODS

We characterized network and nonnetwork factors to explore their association with which FDRs were told about the genetic risk and whether or not relatives underwent genetic testing. Ninety-two female probands with hereditary breast and ovarian cancer who have confirmed BRCA1/2 mutations participated in the study. Communication of hereditary breast and ovarian cancer risk was assessed between 92 probands and their 417 FDRs.

RESULTS

Of 92 probands, 94.5% (n = 87) communicated their genetic test result to at least one of their FDRs. Of FDRs older than 18 years, 19.9% (n = 72) have genetic testing. Emotional closeness, educational level of the proband, and relative's age were significantly associated with communicating test results with FDRs.

CONCLUSION

Communication of genetic risk with the FDRs after having a BRCA1/2 gene-mutation-positive test result was high in this group of cancer patients. However, the rate of genetic testing among FDRs was low.

IMPLICATIONS FOR PRACTICE

Probands' educational level and age of relatives for cascade genetic screening should be considered during counseling. Interventions to support women with BRCA1/2 mutations during the communication process and their family members' engagement in testing and risk-reducing strategies are needed.

Perceptions of genetic testing in patients with hereditary chronic pancreatitis and their families: a qualitative triangulation

Hereditary chronic pancreatitis (HCP) is a genetically determined condition characterized by intermittent acute episodes of pancreatitis and long-term impairment of the exocrine and endocrine pancreatic functions. Genetic test results can have substantial psychological and social consequences for the individuals tested and their families. Nevertheless, little is known so far about the subjective experience of individuals genetically tested for HCP. This qualitative study examines the viewpoints of HCP patients and their relatives in order to identify the psychosocial and ethical implications related to genetic testing within families. Semi-structured qualitative individual interviews and a focus group with HCP patients and their family members were conducted. Data were audio-recorded, transcribed verbatim and analysed using qualitative content analysis. A total of 28 individuals were enrolled in the study: 24 individuals (17 patients, 7 relatives) were interviewed in semi-structured one-on-one interviews and 4 individuals (2 patients, 2 life partners) participated in the focus group. Emerging topics covered (1) genetic testing in childhood, (2) genetic testing within the family and (3) family planning. The study reveals that genetic testing for HCP has a wide influence in familial contexts and is accompanied by normative issues, such as autonomy, reproductive decisions and sharing of information within the family. The results raise the awareness of the complexity of family contexts: familial relationships and dynamics can have great influence on the individual decisions related to genetic testing. Increased understanding of these relational contexts can help health professionals, for example, in counselling, to discuss genetic testing better with patients and families.

Communication about spinal muscular atrophy and genetic risk within families: An Australian pilot study

AIM

In families with a child diagnosed with spinal muscular atrophy (SMA), siblings who do not have SMA could still be genetic carriers of the condition. This study is the first to explore how siblings of patients with SMA learn about the condition and their genetic risk.

METHOD

In-depth, semi-structured interviews were conducted with several parents and unaffected siblings of people with SMA types II and III in Australia. Thematic analysis was performed.

RESULTS

Siblings described learning about SMA gradually over time through conversations with their parents and other sources, including the Internet, biology classes and support groups. Parents and unaffected siblings described challenges in family communication due to the emotional intensity associated with having SMA in the family. Most siblings did not report learning from their family how the inheritance of SMA related to their own genetic carrier risk and possible reproductive implications.

CONCLUSION

Siblings described their parents as being open and honest in communicating about SMA; however, this study found that communication before the age of understanding abstract concepts, in combination with the emotional intensity of SMA, resulted in gaps in knowledge about SMA.

A Modern Dilemma: How Experts Grapple with Ambiguous Genetic Test Results

Objective. Clinicians regularly use panel genetic testing to identify hereditary breast cancer risk, but this practice increases the rate of receiving an ambiguous test result, the variant of uncertain significance (VUS). VUS results are a growing and long-term challenge for providers and have caused negative patient outcomes. The objective of this study was to elicit expert opinions about patients' decision making after receiving a VUS result to provide future guidance for VUS disclosure. Methods. Using an adapted mental models approach, experts (N = 25) completed an online survey and in-depth interview eliciting qualitative judgments of the factors relevant to informed patient decision making after receiving a VUS result. Content analysis of interview transcripts clarified the basis for these judgments. Results. Participants identified 11 decisions facing patients after receiving VUS results grouped into ambiguity management or risk management. The experts also identified 24 factors relevant to each decision, which reflected 2 themes: objective factors (e.g., clinical information, guidelines) and psychosocial factors (e.g., understanding or risk perception). Conclusion. This study presents an adaptation of the mental models approach for communication under conditions of ambiguity. Findings suggest providers who present VUS results from genetic testing for hereditary breast cancer should discuss decisions related to ambiguity management that focus on hope for future reclassification, and be directive when discussing risk management decisions. Objective and psychosocial factors should influence both ambiguity and risk management decisions, but especially risk management decisions.

Social media usage in family communication about genetic information: 'I no longer speak with my sister but she needed to know'

The use of social media has become a ubiquitous form of communication. Little is known about whether social media is used in families to assist with the communication of genetic information. This study aimed to understand if and why individuals use social media to communicate genetic information to at-risk relatives. Individuals with either a pathogenic variant in a cancer-predisposing gene or a heterozygous pathogenic variant in an autosomal or X-linked recessive gene were surveyed about communicating genetic information to their at-risk relatives and their use of social media to assist this process. Surveys were sent to 323 individuals from a reproductive carrier screening program and 250 individuals from a familial cancer center. The 128 responses (response rate 25.2%) showed that while most participants (79.0%) did not use social media to communicate genetic information, those that did use social media (21.0%) found it to be helpful as it was easy, accessible and allowed individuals to overcome communication barriers. Genetic professionals should be aware that social media is being used by individuals to assist family communication about genetic information and should discuss this method of communication with individuals who are faced with communicating genetic information with their family.
