Informed consent for return of incidental findings in genomic research

Parents and Provider Perspectives on the Return of Genomic Findings for Cleft Families in Africa

BACKGROUND

Inadequate knowledge among health care providers (HCPs) and parents of affected children limits the understanding and utility of secondary genetic findings (SFs) in under-represented populations in genomics research. SFs arise from deep DNA sequencing done for research or diagnostic purposes and may burden patients and their families despite their potential health importance. This study aims to evaluate the perspective of both groups regarding SFs and their choices in the return of results from genetic testing in the context of orofacial clefts.

METHODS

Using an online survey, we evaluated the experiences of 252 HCPs and 197 parents across participating cleft clinics in Ghana and Nigeria toward the return of SFs across several domains.

RESULTS

Only 1.6% of the HCPs felt they had an expert understanding of when and how to incorporate genomic medicine into practice, while 50.0% agreed that all SFs should be returned to patients. About 95.4% of parents were willing to receive all the information from genetic testing (including SFs), while the majority cited physicians as their primary information source (64%).

CONCLUSIONS

Overall, parents and providers were aware that genetic testing could help in the clinical management of diseases. However, they cited a lack of knowledge about genomic medicine, uncertain clinical utility, and lack of available learning resources as barriers. The knowledge gained from this study will assist with developing guidelines and policies to guide providers on the return of SFs in sub-Saharan Africa and across the continent.

Perspectives and experiences of researchers regarding feedback of incidental genomic research findings: A qualitative study

Background

There is a plethora of unanswered ethical questions about sharing incidental findings in genetics and genomics research. Yet understanding and addressing such issues is necessary for communicating incidental findings with participants. We explored researchers’ perspectives and experiences regarding feedback of incidental genomics findings to participants.

Methods

This was a qualitative study using semi-structured interview schedules for In-depth interviews. Thirty respondents were purposively selected based on role as genetics and genomics researchers in Uganda. Data were analysed through content analysis to identify emerging themes using a comprehensive thematic matrix. QSR International NVivo software was used to support data analysis.

Results

a). On perceptions, sharing of incidental findings was acceptable and four themes emerged including role of professional judgement; role of ethics committees and ethical guidelines; optimal disclosure practices; limits to professional duty and uncertainty and; b). on practices, sharing had been carried out by some researchers and a theme on experience and practices emerged.

Conclusion

Feedback of incidental genomics research findings to participants is generally acceptable to researchers. Some researchers. Challenges include lack of ethical guidelines and uncertainty about the findings.

Should Feedback of Individual Results be Integrated into the Consent Process in African Genomics? Participants' Views from an HIV-TB Genomics Research Project in Botswana

BACKGROUND

Whilst informed consent is a key component of considering whether individual genomic research results could or should be fed back to research participants, little is known about the views of African research participants on its role.

METHODS

We carried out a qualitative study to explore views of adolescents and parents or caregivers regarding informed consent for feedback of individual results from a genomics research project in Botswana. We conducted 24 deliberative focus group discussions with 93 participants (44 adolescents and 49 parents or caregivers) and 12 in-depth interviews (6 adolescents and 6 parents).

RESULTS

Our findings revealed that most participants would like to be informed about the possibility of discovering individual genetic results during the consent process and that consent be obtained for feedback during the enrollment process. They further expressed that in cases where prior consent to feedback was not obtained, then participants should be re-contacted where life-saving genetic information is discovered. Participants emphasized the need for researchers to ensure that participants' decisions regarding feedback of results are well-informed. Autonomy, transparency, and communication were identified as key values to uphold during the consent process.

CONCLUSION

In conclusion, obtaining participants' consent for feedback of results is important to ensure that their rights and wellbeing are protected in research. This is critical in building trust relationships between participants and researchers.

Whether, when, how, and how much? General public's and cancer patients' views about the disclosure of genomic secondary findings

BACKGROUND

Data on the modalities of disclosing genomic secondary findings (SFs) remain scarce. We explore cancer patients' and the general public's perspectives about disclosing genomic SFs and the modalities of such disclosure.

METHODS

Sixty-one cancer patients (n = 29) and members of the public (n = 32) participated in eight focus groups in Montreal and Quebec City, Canada. They were asked to provide their perspectives of five fictitious vignettes related to medically actionable and non-actionable SFs. Two researchers used a codification framework to conduct a thematic content analysis of the group discussion transcripts.

RESULTS

Cancer patients and members of the public were open to receive genomic SFs, considering their potential clinical and personal utility. They believed that the right to know or not and share or not such findings should remain the patient's decision. They thought that the disclosure of SFs should be made mainly in person by the prescribing clinician. Maintaining confidentiality when so requested and preventing genetic discrimination were considered essential.

CONCLUSION

Participants in this study welcomed the prospect of disclosing genomic SFs, as long as the right to choose to know or not to know is preserved. They called for the development of policies and practice guidelines that aim to protect genetic information confidentiality as well as the autonomy, physical and psychosocial wellbeing of patients and families.

Views on genomic research result delivery methods and informed consent: a review

There has been little discussion of the way genomic research results should be returned and how to obtain informed consent for this. We systematically searched the empirical literature, identifying 63 articles exploring stakeholder perspectives on processes for obtaining informed consent about return of results and/or result delivery. Participants, patients and members of the public generally felt they should choose which results are returned to them and how, ranging from direct (face-to-face, telephone) to indirect (letters, emails, web-based delivery) communication. Professionals identified inadequacies in result delivery processes in the research context. Our findings have important implications for ensuring participants are supported in deciding which results they wish to receive or, if no choice is offered, preparing them for potential research outcomes.

Navigating the Intersection between Genomic Research and Clinical Practice

The Risk Assessment Program (RAP) at Fox Chase Cancer Center (Philadelphia, PA) is a multi-generational prospective cohort, enhanced for personal and family history of cancer, consisting of over 10,000 individuals for whom data on personal and family history of cancer, risk factors, genetic and genomic data, health behaviors, and biospecimens are available. The RAP has a broad research agenda including the characterization of genes with known or potential relevance to cancer, gene-gene and gene-environment interactions, and their contribution to clinically useful risk assessment and risk reduction strategies. Increasingly, this body of research is identifying genetic changes which may have clinical significance for RAP research participants, leading us to confront the issue of whether to return genetic results emerging from research laboratories. This review will describe some of the important fundamental points that must be debated as we develop a paradigm for return of research results. The key issues to address as the scientific community moves toward adopting a policy of return of research results include the best criteria for determining which results to offer, the consent document components necessary to ensure that the participant makes a truly informed decision about receiving their results, and associated logistical and cost challenges.See all articles in this Special Collection Honoring Paul F.

Ethical Issues in Consent for the Reuse of Data in Health Data Platforms

Data platforms represent a new paradigm for carrying out health research. In the platform model, datasets are pooled for remote access and analysis, so novel insights for developing better stratified and/or personalised medicine approaches can be derived from their integration. If the integration of diverse datasets enables development of more accurate risk indicators, prognostic factors, or better treatments and interventions, this obviates the need for the sharing and reuse of data; and a platform-based approach is an appropriate model for facilitating this. Platform-based approaches thus require new thinking about consent. Here we defend an approach to meeting this challenge within the data platform model, grounded in: the notion of 'reasonable expectations' for the reuse of data; Waldron's account of 'integrity' as a heuristic for managing disagreement about the ethical permissibility of the approach; and the element of the social contract that emphasises the importance of public engagement in embedding new norms of research consistent with changing technological realities. While a social contract approach may sound appealing, however, it is incoherent in the context at hand. We defend a way forward guided by that part of the social contract which requires public approval for the proposal and argue that we have moral reasons to endorse a wider presumption of data reuse. However, we show that the relationship in question is not recognisably contractual and that the social contract approach is therefore misleading in this context. We conclude stating four requirements on which the legitimacy of our proposal rests.

Attitudes among South African university staff and students towards disclosing secondary genetic findings

The present study represents an initial step in understanding diverse academic perspectives on the disclosure of secondary findings (SFs) from genetic research conducted in Africa. Using an online survey completed by 674 university students and academic staff in South Africa, we elicited attitudes towards the return of SFs. Latent class analysis (LCA) was performed to classify sub-groups of participants according to their overall attitudes to returning SFs. We did not find substantial differences in attitudes towards the return of findings between staff and students. Overall, respondents were in favour of the return of SFs in genetics research, depending on the type. The majority of survey respondents (80%) indicated that research participants should be given the option of deciding whether to have genetic SFs returned. LCA revealed that the largest group (53%) comprised individuals with more favourable attitudes to the return of SFs in genetics research. Those with less favourable attitudes comprised only 4% of the sample. This study provides important insights that may, together with further empirical evidence, inform the development of research guidelines and policy to assist healthcare professionals and researchers.

Old Challenges or New Issues? Genetic Health Professionals' Experiences Obtaining Informed Consent in Diagnostic Genomic Sequencing

Background

While integrating genomic sequencing into clinical care carries clear medical benefits, it also raises difficult ethical questions. Compared to traditional sequencing technologies, genomic sequencing and analysis is more likely to identify unsolicited findings (UF) and variants that cannot be classified as benign or disease-causing (variants of uncertain significance; VUS). UF and VUS pose new challenges for genetic health professionals (GHPs) who are obtaining informed consent for genomic sequencing from patients.

Methods

We conducted semi-structured interviews with 31 GHPs across Europe, Australia and Canada to identify some of these challenges.

Results

Our results show that GHPs find it difficult to prepare patients to receive results because a vast amount of information is required to fully inform patients about VUS and UF. GHPs also struggle to engage patients – many of whom may be focused on ending their ‘diagnostic odyssey’ – in the informed consent process in a meaningful way. Thus, some questioned how ‘informed’ patients actually are when they agree to undergo clinical genomic sequencing.

Conclusions

These findings suggest a tension remains between sufficient information provision at the risk of overwhelming the patient and imparting less information at the risk of uninformed decision-making. We suggest that a shift away from ‘fully informed consent’ toward an approach aimed at realizing, as far as possible, the underlying goals that informed consent is meant to promote.

Dynamic-informed consent: A potential solution for ethical dilemmas in population sequencing initiatives

While the majority of population-level genome sequencing initiatives claim to follow the principles of informed consent, the requirements for informed consent have not been-well defined in this context. In fact, the implementation of informed consent differs greatly across these initiatives - spanning broad consent, blanket consent, and tiered consent among others. As such, this calls for an investigation into the requirements for consent to be "informed" in the context of population genomics. One particular strategy that claims to be fully informed and to continuously engage participants is called "dynamic consent". Dynamic consent is based on a personalised communication platform that aims to facilitate the consent process. It is oriented to support continuous two-way communication between researchers and participants. In this paper, we analyze the requirements of informed consent in the context of population genomics, review various current implementations of dynamic consent, assess whether they fulfill the requirement of informed consent, and, in turn, enable participants to make autonomous and informed choices on whether or not to participate in research projects.

Stakeholders' perspectives on the post-mortem use of genetic and health-related data for research: a systematic review

The majority of biobank policies and consent forms do not address post-mortem use of data for medical research, thus causing uncertainty after research participants' death. This systematic review identifies studies examining stakeholders' perspectives on this issue. We conducted a search in MEDLINE, CINAHL, EMBASE and Web of Science. Findings were categorised in two themes: (1) views on the use of data for medical research after participants' death, and (2) perspectives regarding the post-mortem return of individual genetic research results. An important subtheme was the appropriate authority and degree of control over posthumous use of data. The sixteen included studies all focused on genetic data and used quantitative and qualitative methods to survey perspectives of research participants, family members, researchers and Institutional Review Board members. Acceptability of post-mortem use of data for medical research was high among research participants and their relatives. Most stakeholders thought participants should be informed about post-mortem research uses during initial consent. Between lay persons and professionals, disagreement exists about whether relatives should receive actionable genetic findings, and whether the deceased's previous preferences can be overridden. We conclude that regulations and ethical guidance should leave room for post-mortem use of personal data for research, provided that informed consent procedures are transparent on this issue, including the return of individual research findings to relatives. Future research is needed to explore underlying causes for differences in views, as well as ethical and legal issues on the appropriate level of control by deceased research participants (while alive) and their relatives.

Parents' motivations, concerns and understanding of genome sequencing: a qualitative interview study

The 100,000 Genomes Project is a hybrid clinical and research project in which patients and parents are offered genome sequencing for cancer and rare and inherited disease diagnosis; all participants receive their main findings and contribute their data for research, and are offered optional secondary findings. Our aim was to explore participating parents' attitudes towards and understanding of genome sequencing in this hybrid context. We conducted in-depth telephone interviews with 20 parents of children with rare diseases participating in the 100,000 Genomes Project. Parents were positive about contributing to research, although some had needed reassurance about data protections. Although most felt positive about secondary findings, some could not recall or misunderstood key aspects. Some were also concerned about potential emotional impact of results and a few raised concerns about life insurance implications, and the impact of future legal changes. Participants were generally positive about consent appointments, but several raised concerns about 'information overload' because of deciding about secondary findings at the same time as about the main diagnostic genome sequencing and data contribution. Additional information resources, particularly online tools, were highlighted as potentially useful ways of supporting the consent process. We conclude that parents offered genome sequencing as part of a national hybrid clinical and research project report many positive attitudes and experiences, but also concerns and misunderstandings. Further research is needed on how best to support informed consent, particularly about secondary findings. Additional resources such as online tools might usefully support future genome sequencing consent processes.

Public Understanding and Opinions regarding Genetic Research on Alzheimer's Disease

BACKGROUND

Participants willing to provide genetic samples are needed to propel research on Alzheimer's disease (AD) treatment and prevention forward. A limited public understanding of what AD genetic research entails and concerns about participation may constitute recruitment challenges.

OBJECTIVES

This study seeks to understand how well older adults understand AD genetic research and whether their understanding is related to concerns about participation or willingness to engage.

METHODS

Our surveys included a mock consent form with corresponding knowledge and opinion questions regarding AD. The surveys were mailed to participants from the University of Kentucky Alzheimer's Disease Center and to a list of randomly selected individuals within the same age range from a local voter registration list. Descriptive and multivariable linear regression analyses were conducted.

RESULTS

The returned surveys (n = 502) demonstrated limits to what the respondents understood immediately after reading the relevant material, with a mean summary knowledge score of 74.5 out of 100. While comprehension gaps were not related to level of concern or willingness to engage, concerns were related to willingness to engage. Concerns were greater among individuals not actively involved in research, individuals from minority groups, and those with higher levels of education.

CONCLUSIONS

Focusing on concerns specifically, rather than on knowledge more generally, may help increase participation.

Much ado about nothing: A qualitative study of the experiences of an average-risk population receiving results of exome sequencing

The increasing availability of exome sequencing to the general ("healthy") population raises questions about the implications of genomic testing for individuals without suspected Mendelian diseases. Little is known about this population's motivations for undergoing exome sequencing, their expectations, reactions, and perceptions of utility. In order to address these questions, we conducted in-depth semi-structured interviews with 12 participants recruited from a longitudinal multi-omics profiling study that included exome sequencing. Participants were interviewed after receiving exome results, which included Mendelian disease-associated pathogenic and likely pathogenic variants, pharmacogenetic variants, and risk assessments for multifactorial diseases such as type 2 diabetes. The primary motivation driving participation in exome sequencing was personal curiosity. While they reported feeling validation and relief, participants were frequently underwhelmed by the results and described having expected more from exome sequencing. All participants reported discussing the results with at least some family, friends, and healthcare providers. Participants' recollection of the results returned to them was sometimes incorrect or incomplete, in many cases aligning with their perceptions of their health risks when entering the study. These results underscore the need for different genetic counseling approaches for generally healthy patients undergoing exome sequencing, in particular the need to provide anticipatory guidance to moderate participants' expectations. They also provide a preview of potential challenges clinicians may face as genomic sequencing continues to scale-up in the general population despite a lack of full understanding of its impact.

Informed Consent in Biomedical Research

Informed consent is the result of tumultuous events in both the clinical and research arenas over the last 100 years. Throughout this time, the notion of informed consent has shifted tremendously, both due to advances in medicine, as well as the type of data being gathered. As such, informed consent has misaligned with the goals of medical research. It is becoming more and more vital to address this chasm, and begin building new frameworks to link this disconnect. Thus, we address three goals in this paper. First, we discuss the history of informed consent and unify the varying definitions of the term. Second, we evaluate the current research on the topic, classify them into themes, and attend to the problems therein. Lastly, we employ these themes of informed consent research mentioned previously to provide guidance and insight for future research in the arena.

How do clinical genetics consent forms address the familial approach to confidentiality and incidental findings? A mixed-methods study

Genetic test results can be relevant to patients and their relatives. Questions thus arise around whether clinicians regard genetic information as confidential to individuals or to families, and about how they broach this and other issues, including the potential for incidental findings, in consent (forms) for genetic testing. We conducted a content analysis of UK-wide genetic testing consent forms and interviewed 128 clinicians/laboratory scientists. We found that almost all genetic services offered patients multiple, sometimes unworkable, choices on forms, including an option to veto the use of familial genetic information to benefit relatives. Participants worried that documented choices were overriding professional judgement and cautioned against any future forms dictating practice around incidental findings. We conclude that ‘tick-box’ forms, which do little to enhance autonomy, are masking valid consent processes in clinical practice. As genome-wide testing becomes commonplace, we must re-consider consent processes, so that they protects patients’—and relatives’—interests.

Experiences and perspectives on the return of secondary findings among genetic epidemiologists

PURPOSE

While there has been a recent increase in scholarship around developing policies for the return of results from genetic sequencing, it is not clear whether these approaches are appropriate for genetic epidemiology studies. Because genetic epidemiological research increasingly utilizes genome sequencing methods, particularly in large data sets where researchers did not directly ascertain the subjects, it is important to understand researchers' perspectives on the return of results.

METHODS

We conducted an online survey of members of the International Genetic Epidemiology Society to document the diversity of experiences and impressions regarding return of results. The survey contained both closed and open-ended questions.

RESULTS

Among our respondents who enroll their own research participants, only 21% return secondary findings. Most respondents do not search their sequence data for clinically actionable findings not associated with their disease of interest. Many feel that genetic epidemiologists have a unique perspective on the return of results and that research studies should not follow the same procedures as clinical sequencing studies.

CONCLUSION

Precision medicine initiatives that rely on both clinical and "big data" genomic research should account for variation in researcher perspectives and study design limitations when developing policies and standard practices regarding the return of results.

Evaluation of Recipients of Positive and Negative Secondary Findings Evaluations in a Hybrid CLIA-Research Sequencing Pilot

While consensus regarding the return of secondary genomic findings in the clinical setting has been reached, debate about such findings in the research setting remains. We developed a hybrid, research-clinical translational genomics process for research exome data coupled with a CLIA-validated secondary findings analysis. Eleven intramural investigators from ten institutes at the National Institutes of Health piloted this process. Nearly 1,200 individuals were sequenced and 14 secondary findings were identified in 18 participants. Positive secondary findings were returned by a genetic counselor following a standardized protocol, including referrals for specialty follow-up care for the secondary finding local to the participants. Interviews were undertaken with 13 participants 4 months after receipt of a positive report. These participants reported minimal psychologic distress within a process to assimilate their results. Of the 13, 9 reported accessing the recommended health care services. A sample of 107 participants who received a negative findings report were surveyed 4 months after receiving it. They demonstrated good understanding of the negative secondary findings result and most expressed reassurance (64%) from that report. However, a notable minority (up to 17%) expressed confusion regarding the distinction of primary from secondary findings. This pilot shows it is feasible to couple CLIA-compliant secondary findings to research sequencing with minimal harms. Participants managed the surprise of a secondary finding with most following recommended follow up, yet some with negative findings conflated secondary and primary findings. Additional work is needed to understand barriers to follow-up care and help participants distinguish secondary from primary findings.

Secondary findings from whole-exome/genome sequencing evaluating stakeholder perspectives. A review of the literature

With the development of next generation sequencing, beyond identifying the cause of manifestations that justified prescription of the test, other information with potential interest for patients and their families, defined as secondary findings (SF), can be provided once patients have given informed consent, in particular when therapeutic and preventive options are available. The disclosure of such findings has caused much debate. The aim of this work was to summarize all opinion-based studies focusing on SF, so as to shed light on the concerns that this question generate. A review of the literature was performed, focusing on all PubMed articles reporting qualitative, quantitative or mixed studies that interviewed healthcare providers, participants, or society regarding this subject. The methodology was carefully analysed, in particular whether or not studies made the distinction between actionable and non-actionable SF, in a clinical or research context. From 2010 to 2016, 39 articles were compiled. A total of 14,868 people were interviewed (1259 participants, 6104 healthcare providers, 7505 representatives of society). When actionable and non-actionable SF were distinguished (20 articles), 92% of respondents were keen to have results regarding actionable SF (participants: 88%, healthcare providers: 86%, society: 97%), against 70% (participants: 83%, healthcare providers: 62%, society: 73%) for non-actionable SF. These percentages were slightly lower in the specific situation of children probands. For respondents, the notion of the «patient's choice» is crucial. For healthcare providers, the importance of defining policies for SF among diagnostic lab, learning societies and/or countries is outlined, in particular regarding the content and extension of the list of actionable genes to propose, the modalities of information, and the access to information about adult-onset diseases in minors. However, the existing literature should be taken with caution, since most articles lack a clear definition of SF and actionability, and referred to hypothetical scenarios with limited information to respondents. Studies conducted by multidisciplinary teams involving patients with access to results are sadly lacking, in particular in the medium term after the results have been given. Such studies would feed the debate and make it possible to measure the impact of such findings and their benefit-risk ratio.

Return of individual results in epilepsy genomic research: A view from the field

Genomic findings are emerging rapidly in 2 large, closely related epilepsy research consortia: the Epilepsy Phenome/Genome Project and Epi4K. Disclosure of individual results to participants in genomic research is increasingly viewed as an ethical obligation, but strategies for return of results were not included in the design of these consortia, raising complexities in establishing criteria for which results to offer, determining participant preferences, managing the large number of sites involved, and covering associated costs. Here, we describe the challenges faced, alternative approaches considered, and progress to date. Experience from these 2 consortia illustrates the importance, for genomic research in epilepsy and other disorders, of including a specific plan for return of results in the study design, with financial support for obtaining clinical confirmation and providing ongoing support for participants. Participant preferences for return of results should be established at the time of enrollment, and methods for allowing future contacts with participants should be included. In addition, methods should be developed for summarizing meaningful, comprehensible information about findings in the aggregate that participants can access in an ongoing way.

The development of large-scale de-identified biomedical databases in the age of genomics-principles and challenges

Contemporary biomedical databases include a wide range of information types from various observational and instrumental sources. Among the most important features that unite biomedical databases across the field are high volume of information and high potential to cause damage through data corruption, loss of performance, and loss of patient privacy. Thus, issues of data governance and privacy protection are essential for the construction of data depositories for biomedical research and healthcare. In this paper, we discuss various challenges of data governance in the context of population genome projects. The various challenges along with best practices and current research efforts are discussed through the steps of data collection, storage, sharing, analysis, and knowledge dissemination.

How do providers discuss the results of pediatric exome sequencing with families?

AIM

This study provides preliminary data on the process and content of returning results from exome sequencing offered to children through one of the Clinical Sequencing Exploratory Research (CSER) projects.

MATERIALS & METHODS

We recorded 25 sessions where providers returned diagnostic and secondary sequencing results to families. Data interpretation utilized inductive thematic analysis.

RESULTS

Typically, providers followed a results report and discussed diagnostic findings using technical genomic and sequencing concepts. We identified four provider processes for returning results: teaching genetic concepts; assessing family response; personalizing findings; and strengthening patient-provider relationships.

CONCLUSION

Sessions should reflect family interest in medical management and next steps, and minimize detailed genomic concepts. As the scope and complexity of sequencing increase, the traditional information-laden counseling model requires revision.

Social and Communicative Functions of Informed Consent Forms in East Asia and Beyond

The recent research and technology development in medical genomics has raised new issues that are profoundly different from those encountered in traditional clinical research for which informed consent was developed. Global initiatives for international collaboration and public participation in genomics research now face an increasing demand for new forms of informed consent which reflect local contexts. This article analyzes informed consent forms (ICFs) for genomic research formulated by four selected research programs and institutes in East Asia – the Medical Genome Science Program in Japan, Universiti Sains Malaysia Human Research Ethics Committee in Malaysia, and the Taiwan Biobank and the Taipei Medical University- Joint Institutional Review Board in Taiwan. The comparative text analysis highlights East Asian contexts as distinct from other regions by identifying communicative and social functions of consent forms. The communicative functions include re-contact options and offering interactive support for research participants, and setting opportunities for family or community engagement in the consent process. This implies that informed consent cannot be validated solely with the completion of a consent form at the initial stage of the research, and informed consent templates can facilitate interactions between researchers and participants through (even before and after) the research process. The social functions consist of informing participants of possible social risks that include genetic discrimination, sample and data sharing, and highlighting the role of ethics committees. Although international ethics harmonization and the subsequent coordination of consent forms may be necessary to maintain the quality and consistency of consent process for data-intensive international research, it is also worth paying more attention to the local values and different settings that exist where research participants are situated for research in medical genomics. More than simply tools to gain consent from research participants, ICFs function rather as a device of social communication between research communities and civic communities in liaison with intermediary agents like ethics committees, genetic counselors, and public biobanks and databases.

The Precision Medicine Nation

The United States' ambitious Precision Medicine Initiative proposes to accelerate exponentially the adoption of precision medicine, an approach to health care that tailors disease diagnosis, treatment, and prevention to individual variability in genes, environment, and lifestyle. It aims to achieve this by creating a cohort of volunteers for precision medicine research, accelerating biomedical research innovation, and adopting policies geared toward patients' empowerment. As strategies to implement the PMI are formulated, critical consideration of the initiative's ethical and sociopolitical dimensions is needed. Drawing on scholarship of nationalism and democracy, we discuss the PMI's construction of what we term "genomic citizenship"; the possible normative obligations arising therefrom; and the ethical, legal, and social challenges that will ensue. Although the PMI is a work in progress, discussion of the existing and emerging issues can facilitate the development of policies, structures, and procedures that can maximize the initiative's ability to produce equitable and socially sensitive outcomes. Our analysis can also be applied to other population-based, precision medicine research programs.

Informed consent for next-generation nucleotide sequencing studies: Aiding communication between participants and investigators

INTRODUCTION

Obtaining informed consent from prospective participants for research studies that include next-generation nucleotide sequencing (NGS) presents significant challenges because of the need to explain all the potential implications of participating, including the possible return of "incidental" findings, in easy-to-understand language.

METHODS AND RESULTS

After reviewing the consent processes at other institutions, we decided to supplement the protocol-specific informed consent form with the following: (1) a short pamphlet for the prospective participant that includes a series of questions that she or he is encouraged to ask the investigator, and (2) a more detailed companion guide for investigators to help them develop simple-language answers to the questions. Both documents are available to use or modify.

CONCLUSIONS

We propose an approach to obtaining informed consent for NGS studies that encourages discussion of key issues without creating a complex, comprehensive document for participants; it also maximizes investigator flexibility. We also suggest mechanisms to return restricted information to participants.

A risk-based framework for biomedical data sharing

The problem of biomedical data sharing is a form of gambling; on one hand it incurs the risk of privacy violations and on the other it stands to profit from knowledge discovery. In general, the risk of granting data access to a user depends heavily upon the data requested, the purpose for the access, the user requesting the data (user motives) and the security of the user's environment. While traditional manual biomedical data sharing processes (based on institutional review boards) are lengthy and demanding, the automated ones (known as honest broker systems) disregard the individualities of different requests and offer "one-size-fits-all" solutions to all data requestors. In this manuscript, we propose a conceptual risk-aware data sharing system; the system brings the concept of risk, from all contextual information surrounding a data request, into the data disclosure decision module. The decision module, in turn, imposes mitigation measures to counter the calculated risk.

The Advantages and Challenges of Testing Children for Heritable Predisposition to Cancer

The increased application of germline genetic testing is expanding our understanding of the risk factors associated with childhood cancer development, and, in some cases, such testing is also informing clinical management. Nonetheless, the incorporation of genetic testing into the pediatric oncology setting is complex and associated with many ethical and practical challenges. The decision as to whether to pursue clinical genetic testing for hereditary cancer predisposition for children should always be guided by the best interest of the child. Despite this fundamental ethical principle, patients, parents, and health care providers may differ in their opinions. Clinical genetic testing to detect the presence of predisposition syndromes associated with childhood-onset cancers, particularly those for which surveillance and preventive measures have proven to enhance outcome, is currently well accepted. On the other hand, clinical genetic testing of children for syndromes associated with adult-onset cancers has raised many concerns about the potential for psychological harm and disrespect of patient autonomy. As a consequence, such testing is not encouraged. The challenges surrounding germline genetic testing are further complicated when testing is done in the research setting and/or when it involves whole-exome or whole-genome sequencing approaches, which can uncover genetic variants that may or may not be associated with the disease under study. Accordingly, there is great debate around these processes and the most appropriate approaches regarding the return of test results. Future research is needed to enhance knowledge about how best to incorporate genomic information into clinical practice.

Privacy and confidentiality measures in genetic testing and counselling: arguing on genetic exceptionalism again?

Medical confidentiality in clinical genetics poses an important question about its scope, which would be in line with professional ethics and simple honesty. It is already known that the maintenance of absolute anonymity, bearing in mind the current progress of genetic techniques, is virtually impossible. On the other hand, our insight into the information contained in the human genome is increasing. This mini-review presents the authors' standpoint regarding this complex and difficult issue.

Stakeholder views on secondary findings in whole-genome and whole-exome sequencing: a systematic review of quantitative and qualitative studies

PURPOSE

As whole-exome sequencing (WES) and whole-genome sequencing (WGS) move into routine clinical practice, it is timely to review data that might inform the debate regarding secondary findings (SF) and the development of policies that maximize participant benefit.

METHODS

We systematically searched for qualitative and quantitative studies that explored stakeholder views on SF in WES/WGS. Framework analysis was undertaken to identify major themes.

RESULTS

Forty-four articles reporting the views of 11,566 stakeholders were included. Stakeholders were broadly supportive of returning "actionable" findings, but definitions of actionability varied. Stakeholder views on SF disclosure exist along a spectrum: potential WES/WGS recipients' views were largely influenced by a sense of rights, whereas views of genomics professionals were informed by a sense of professional responsibility. Experience with genetic illness and testing resulted in greater caution about SF, suggesting that truly informed decisions require an understanding of the implications and limitations of WES/WGS and possible findings.

CONCLUSION

This review suggests that bidirectional interaction during consent might best facilitate informed decision making about SF and that dynamic forms of consent, allowing for changing preferences, should be considered. Research exploring views from wider perspectives and from recipients who have received SF is critical if evidence-based policies are to be achieved.Genet Med 19 3, 283-293.

Clinical Sequencing Exploratory Research Consortium: Accelerating Evidence-Based Practice of Genomic Medicine

Despite rapid technical progress and demonstrable effectiveness for some types of diagnosis and therapy, much remains to be learned about clinical genome and exome sequencing (CGES) and its role within the practice of medicine. The Clinical Sequencing Exploratory Research (CSER) consortium includes 18 extramural research projects, one National Human Genome Research Institute (NHGRI) intramural project, and a coordinating center funded by the NHGRI and National Cancer Institute. The consortium is exploring analytic and clinical validity and utility, as well as the ethical, legal, and social implications of sequencing via multidisciplinary approaches; it has thus far recruited 5,577 participants across a spectrum of symptomatic and healthy children and adults by utilizing both germline and cancer sequencing. The CSER consortium is analyzing data and creating publically available procedures and tools related to participant preferences and consent, variant classification, disclosure and management of primary and secondary findings, health outcomes, and integration with electronic health records. Future research directions will refine measures of clinical utility of CGES in both germline and somatic testing, evaluate the use of CGES for screening in healthy individuals, explore the penetrance of pathogenic variants through extensive phenotyping, reduce discordances in public databases of genes and variants, examine social and ethnic disparities in the provision of genomics services, explore regulatory issues, and estimate the value and downstream costs of sequencing. The CSER consortium has established a shared community of research sites by using diverse approaches to pursue the evidence-based development of best practices in genomic medicine.

Raising Genomic Citizens: Adolescents and the Return of Secondary Genomic Findings

Whole genome and exome sequencing (WGS/WES) techniques raise hope for a new scale of diagnosis, prevention, and prediction of genetic conditions, and improved care for children. For these hopes to materialize, extensive genomic research with children will be needed. However, the use of WGS/WES in pediatric research settings raises considerable challenges for families, researchers, and policy development. In particular, the possibility that these techniques will generate genetic findings unrelated to the primary goal of sequencing has stirred intense debate about whether, which, how, and when these secondary or incidental findings (SFs) should be returned to parents and minors. The debate is even more pronounced when the subjects are adolescents, for whom decisions about return of SFs may have particular implications. In this paper, we consider the rise of "genomic citizenship" and the main challenges that arise for these stakeholders: adolescents' involvement in decisions relating to return of genomic SFs, the types of SFs that should be offered, privacy protections, and communication between researchers and adolescents about SFs. We argue that adolescents' involvement in genomic SF-related decisions acknowledges their status as valuable stakeholders without detracting from broader familial interests, and promotes more informed genomic citizens.

Understanding the Psychosocial Effects of WES Test Results on Parents of Children with Rare Diseases

The use of whole exome sequencing (WES) for diagnostics of children with rare genetic diseases raises questions about best practices in genetic counselling. While a lot of attention is now given to pre-test counselling procedures for WES, little is known about how parents experience the (positive, negative, or inconclusive) WES results in daily life. To fill this knowledge gap, data were gathered through in-depth interviews with parents of 15 children who underwent WES analysis. WES test results, like results from other genetic tests, evoked relief as well as worries, irrespective of the type of result. Advantages of obtaining a conclusive diagnosis included becoming more accepting towards the situation, being enabled to attune care to the needs of the child, and better coping with feelings of guilt. Disadvantages experienced included a loss of hope for recovery, and a loss by parents of their social network of peers and the effort necessary to re-establish that social network. While parents with conclusive diagnoses were able to re-establish a peer community with the help of social media, parents receiving a possible diagnosis experienced hurdles in seeking peer support, as peers still needed to be identified. These types of psychosocial effects of WES test results for parents are important to take into account for the development of successful genetic counselling strategies.

Parents' Perspectives on Supporting Their Decision Making in Genome-Wide Sequencing

PURPOSE

The purpose of this study was to explore parents' perceptions of their decisional needs when considering genome-wide sequencing (GWS) for their child. This is a partial report and focuses on how parents prefer to receive education and information to support their decision making about GWS.

DESIGN

This study adopted an interpretive description qualitative methodological approach and used the concept of shared decision making and the Ottawa Decision Support Framework.

METHODS

Participants were parents who had already consented to GWS, and had children with undiagnosed conditions that were suspected to be genetic in origin. Fifteen parents participated in a focus group or individual interview. Transcriptions were analyzed concurrently with data collection, iteratively, and constantly compared to one another. Repeat interviews were conducted with five of the parents to confirm, challenge, or expand on the developing concepts.

FINDINGS

Participants felt that their decision to proceed with GWS for their child was an easy one. However, they expressed some unresolved decisional needs, including a lack of knowledge about certain topics that became relevant and important to them later and a need for more support and resources. Participants also had ongoing informational and psychosocial needs after the single clinical encounter where their decision making occurred.

CONCLUSIONS

Participants expressed unmet decisional needs, which may have influenced the quality of their decisions. The strategies that participants suggested may help create parent-tailored education, counseling, decision support, and informed consent processes.

CLINICAL RELEVANCE

Health care professionals who offer GWS for children should assess parents' values, priorities, and informational needs and tailor information accordingly. There are opportunities for nurses to become involved in supporting families who are considering GWS for their child.

Illustrative case studies in the return of exome and genome sequencing results

Whole genome and exome sequencing tests are increasingly being ordered in clinical practice, creating a need for research exploring the return of results from these tests. A goal of the Clinical Sequencing and Exploratory Research (CSER) consortium is to gain experience with this process to develop best practice recommendations for offering exome and genome testing and returning results. Genetic counselors in the CSER consortium have an integral role in the return of results from these genomic sequencing tests and have gained valuable insight. We present seven emerging themes related to return of exome and genome sequencing results accompanied by case descriptions illustrating important lessons learned, counseling challenges specific to these tests and considerations for future research and practice.

Genome-Wide Sequencing for Prenatal Detection of Fetal Single-Gene Disorders

New sequencing methods capable of rapidly analyzing the genome at increasing resolution have transformed diagnosis of single-gene or oligogenic genetic disorders in pediatric and adult medicine. Targeted tests, consisting of disease-focused multigene panels and diagnostic exome sequencing to interrogate the sequence of the coding regions of nearly all genes, are now clinically offered when there is suspicion for an undiagnosed genetic disorder or cancer in children and adults. Implementation of diagnostic exome and genome sequencing tests on invasively and noninvasively obtained fetal DNA samples for prenatal genetic diagnosis is also being explored. We predict that they will become more widely integrated into prenatal care in the near future. Providers must prepare for the practical, ethical, and societal dilemmas that accompany the capacity to generate and analyze large amounts of genetic information about the fetus during pregnancy.

Genomic Testing: a Genetic Counselor's Personal Reflection on Three Years of Consenting and Testing

Whole exome sequencing (WES) is increasingly used in research and clinical genetics as the cost of sequencing decreases and the interpretation improves. Genetic counselors need to be prepared to counsel a diverse patient population for this complex test. This commentary is a reflection of one genetic counselor's experiences in counseling, consenting, and returning results for clinical and research WES for over 120 participants and patients. She reflects on how she overcame the initial challenges and concerns of counseling for WES and how her counseling evolved from a teaching based counseling model to an interactive patient-center counseling model. Her insights are offered to prepare other genetic counselors for the growing use of genomic testing.

Overcoming challenges to meaningful informed consent for whole genome sequencing in pediatric cancer research

BACKGROUND

Introducing whole genome sequencing (WGS) into pediatric cancer research at diagnosis poses unique challenges related to informed consent. WGS requires tissue obtained prior to initiating treatment, when families may be overwhelmed with uncertainty and fear. Motivation to participate may be high without fully understanding the range of possible results, including secondary findings. Little is known about parental knowledge, attitudes, and beliefs about this type of research.

PROCEDURE

A qualitative study was conducted to investigate parental knowledge about genetic concepts and WGS, thoughts about the informed consent process, and preferences for secondary findings. Focus groups were conducted with parents/guardians of children with cancer and semi-structured interviews were conducted in a control group without cancer. All transcripts were analyzed using content analysis.

RESULTS

Four focus groups included 15 participants; eight semi-structured interviews included 10 participants. Basic knowledge about genetics was limited to heredity. Some knowledge of genomic analysis was present in 3/15 focus group participants. Major factors related to participation in WGS research were: (i) hope for their child and future children; (ii) no additional procedures; (iii) and protection of privacy. All favored a two-step consent process, first to store extra tissue from a diagnostic biopsy/resection, followed by consenting to WGS research, one-to-two months later. The desire to receive secondary findings was high among both groups, but there were individuals who did not want these results, fearing increased anxiety.

CONCLUSIONS

Parents/guardians of children with cancer have limited knowledge about WGS. A two-step consent process may improve their ability to provide meaningful informed consent.

Evaluating a counselling strategy for diagnostic WES in paediatric neurology: an exploration of parents' information and communication needs

As whole exome sequencing (WES) is just starting to be used as a diagnostic tool in paediatric neurology for children with a neurological disorder, and patient experiences and preferences with regard to counselling are relatively underexplored. This article explores experiences and preferences of parents with pre-test and post-test counselling in a trial that uses WES for diagnostics. Second, it maps information and communication needs which exceed the counselling protocol, in order to acquire insight into how it can be improved. Data were gathered through in-depth interviews with parents of 15 children who were included in the trial. Information and communication needs of parents differed from the protocol with respect to (i) the type and amount of information provided about WES research, (ii) incidental findings, (iii) communication about progress of the study, and (iv) the communication of the results. Furthermore, parents preferred to have more of a communicative exchange with health care providers about their daily struggles and concerns related to their life with a diseased child and wanted to know how a diagnosis could offer help. There are different ways to meet parental needs, but we suggest that assigning a case manager might be a helpful option that deserves further exploration.

"Not Tied Up Neatly with a Bow": Professionals' Challenging Cases in Informed Consent for Genomic Sequencing

As the use of genomic technology has expanded in research and clinical settings, issues surrounding informed consent for genome and exome sequencing have surfaced. Despite the importance of informed consent, little is known about the specific challenges that professionals encounter when consenting patients or research participants for genomic sequencing. We interviewed 29 genetic counselors and research coordinators with considerable experience obtaining informed consent for genomic sequencing to understand their experiences and perspectives. As part of this interview, 24 interviewees discussed an informed consent case they found particularly memorable or challenging. We analyzed these case examples to determine the primary issue or challenge represented by each case. Challenges fell into two domains: participant understanding, and facilitating decisions about testing or research participation. Challenges related to participant understanding included varying levels of general and genomic literacy, difficulty managing participant expectations, and contextual factors that impeded participant understanding. Challenges related to facilitating decision-making included complicated family dynamics such as disagreement or coercion, situations in which it was unclear whether sequencing research would be a good use of participant time or resources, and situations in which the professional experienced disagreement or discomfort with participant decisions. The issues highlighted in these case examples are instructive in preparing genetics professionals to obtain informed consent for genomic sequencing.

Association of Researcher Characteristics with Views on Return of Incidental Findings from Genomic Research

Whole exome/ genome sequencing (WES/WGS) is now commonly used in research and is increasingly used in clinical care to identify the genetic basis of rare and unknown diseases. The management of incidental findings (IFs) generated through these analyses is debated within the research community. To examine how views regarding genomic research IFs are associated with researcher characteristics and experiences, we surveyed genetic professionals and assessed the effect of professional background and experience on their opinions. Researchers who did not have clinical training, provide clinical care to research participants, or have prior experience returning research results were in general more inclined to offer return of IFs than their colleagues with these characteristics. Understanding this will be important to fully appreciate the impact that policies on return of genetic IFs could have on participants, researchers, and genomic research.

Researchers' views on informed consent for return of secondary results in genomic research

PURPOSE

Previous studies have suggested that genomic investigators generally favor offering to return at least some secondary findings to participants and believe that participants' preferences should determine the information they receive. We surveyed investigators to ascertain their views on four models of informed consent for this purpose: traditional consent, staged consent, mandatory return, and outsourced consent.

METHODS

We performed an online survey of the views regarding return of secondary results held by 198 US genetic researchers drawn from our subject pool for an earlier study. Potential participants were identified through the National Institutes of Health RePORTER database and abstracts from the 2011 American Society of Human Genetics meeting.

RESULTS

Under circumstances in which resource constraints are not an issue, approximately a third of respondents would endorse either staged consent or traditional consent; outsourced consent and mandatory return are favored by only a small minority. However, taking resource constraints into account, roughly half the sample would favor traditional consent, with support for staged consent dropping to 13%.

CONCLUSION

Despite their liabilities, traditional approaches to consent are seen as the most viable under current circumstances. However, there is considerable interest in staged consent, assuming the infrastructure to support it can be provided.

Defining and managing incidental findings in genetic and genomic practice

The rapidly declining costs and increasing speeds of whole-genome analysis mean that genetic testing is undergoing a shift from targeted approaches to broader ones that look at the entire genome. As whole-genome technologies gain widespread use, questions about the management of so-called incidental findings-those unrelated to the question being asked-need urgent consideration. In this review, we bring together current understanding and arguments about (1) appropriate terminology, (2) the determination of clinical utility and when to disclose incidental findings, (3) the differences in management and disclosure in clinical, research and commercial contexts and (4) ethical and practical issues about familial implications and recontacting those tested. We recommend that greater international consensus is developed around the disclosure and management of incidental findings, with particular attention to when, and how, less clear-cut results should be communicated. We suggest that there is no single term that captures all the issues around these kinds of findings and that different terms may, therefore, need to be used in different settings. We also encourage the use of clear consent processes, but suggest that the absence of consent should not always preclude disclosure. Finally, we recommend further research to identify ways to implement the use of a genome output as a resource, accessible over time, to facilitate appropriate disclosure and recontact when the significance of a previously unclear incidental finding is clarified.
