Abstract
AIM To determine the attitudes of pregnant couples toward carrier screening genomic tests. METHODS A validated 22-item questionnaire was offered in person by medical staff to pregnant women ≥32 weeks' gestation and their partners attending prenatal classes from May to July 2014. The questionnaire inquired about demographic data, interest in various forms of genetic carrier screening tests, and genetic literacy. RESULTS Of 497 respondents, 69% expressed strong interest in carrier screening. The interested respondents exhibited substantial support for screening for common (82%) or all known genetic diseases (79%), as well as for treatable (79%) and untreatable diseases (85%). The majority of respondents believed that genetic test results could provide them with a sense of security but also provoke anxiety and fear. They were aware that these results could affect their perspective on life, work, and the atmosphere within their family, and acknowledged the potential effect on their relationship with their partner. However, none of these concerns diminished their desire to learn about their carrier status. Respondents with higher genetic literacy exhibited greater interest in screening tests (P=0.006). More non-religious respondents compared with practicing religious respondents (P=0.002), and more respondents with higher education compared with those with lower education, expressed interest in screening (P=0.003). CONCLUSION Most respondents expressed considerable interest in receiving information about their carrier status through genetic tests.

Abstract
Despite the growing popularity of direct-to-consumer genetic testing, there is minimal South African literature on the topic. The limited available research suggests that direct-to-consumer genetic testing is unregulated. However, we suggest that direct-to-consumer genetic testing is indeed regulated, and unusually so. The first step in the process - the collection of a saliva sample by consumers themselves - is unlawful on a plain reading of the National Health Act 61 of 2003 and the Regulations Relating to the Use of Human Biological Material. This is because these statutes require that certain healthcare professionals must remove saliva for genetic testing. Yet, on closer analysis, such an apparent ban on the self-collection of saliva is neither aligned with a purposive interpretation of the relevant legislation, nor would it survive constitutional scrutiny - as it impedes an individual's autonomy. It is concluded that, contrary to a plain reading of the relevant statutes, individuals can lawfully collect their own saliva for direct-to-consumer genetic testing. To provide legal clarity we recommend that the relevant provisions of the National Health Act 61 of 2003 and Regulations Relating to the Use of Human Biological the Material be amended to allow individuals to collect their own saliva samples.

Abstract
Given increased prevalence of direct-to-consumer (DTC) genetic health tests in recent years, this paper delves into discourses among researchers at professional genomics conferences and lay DTC genetic test users on popular discussion website Reddit to understand the contested value of genetic knowledge and its direct implications for health management. Harnessing ethnographic observations at five conferences and a text -analysis of 52 Reddit threads, we find both experts and lay patient-consumers navigate their own versions of “productive uncertainty.” Experts develop genetic technologies to legitimize unsettled genomics as medical knowledge and mobilize resources and products, while lay patient-consumers turn to Internet forums to gain clarity on knowledge gaps that help better manage their genetic risk states. By showing how the uncertain nature of genomics serves as a productive force placing both parties within a mutually cooperative cycle, we argue that experts and patient-consumers co-produce a form of relational medicalization that concretizes “risk” itself as a disease state.

Clinical Practice Guidelines Using GRADE and AGREE II for the Impact of Genetic Variants on Plasma Lipid/Lipoprotein/Apolipoprotein Responsiveness to Omega-3 Fatty Acids. Front Nutr 2022; 8:768474. [PMID: 35237638 PMCID: PMC8883048 DOI: 10.3389/fnut.2021.768474] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2021] [Accepted: 12/20/2021] [Indexed: 12/18/2022] Open
Abstract
Background A recent systematic review, which used the GRADE methodology, concluded that there is strong evidence for two gene-diet associations related to omega-3 and plasma triglyceride (TG) responses. Systematic reviews can be used to inform the development of clinical practice guidelines (CPGs). Objective To provide guidance for clinical practice related to genetic testing for evaluating responsiveness to dietary/supplemental omega-3s and their impact on plasma lipids/lipoproteins/apolipoproteins. Design Using the results of the abovementioned systematic review, the first CPGs in nutrigenetics were developed using the established GRADE methodology and AGREE II approach. Results Three clinical practice recommendations were developed. Most gene-diet associations identified in the literature lack adequate scientific and clinical validity to warrant consideration for implementing in a practice setting. However, two gene-diet associations with strong evidence (GRADE quality: moderate and high) can be considered for implementation into clinical practice in certain cases: male APOE-E4 carriers (rs429358, rs7412) and TG changes in response to the omega-3 fatty acids eicosapentaenoic acid (EPA) and/or docosahexaenoic acid (DHA) as well as a 31-SNP nutrigenetic risk score and TG changes in response to EPA+DHA among adults with overweight/obesity. Ethical and regulatory implications must be considered when providing APOE nutrigenetic tests given the well-established link between APOE genetic variation and Alzheimer's Disease. Conclusion Most of the evidence in this area is not ready for implementation into clinical practice primarily due to low scientific validity (low quality of evidence). However, the first CPGs in nutrigenetics have been developed for two nutrigenetic associations with strong scientific validity, related to dietary/supplemental omega-3 and TG responses.

Abstract
ELSI (Ethical, Legal, and Social Issues) is a widely used acronym in the bioethics literature that encompasses a broad range of research examining the various impacts of science and technology on society. In Canada, GE3LS (Genetics, Ethical, Economic, Environmental, Legal, Social issues) is the term used to describe ELSI studies in the context of genetics and genomics research. It is intentionally more expansive in that GE3LS explicitly brings economic and environmental issues under its purview. ELSI/GE3LS research is increasingly relevant in recent years as there has been a greater emphasis on "translational research" that moves genomic discoveries from the bench to the clinic. The purpose of this chapter is to outline a range of ELSI-related work that might be conducted as part of a large scale genetics or genomics research project, and to provide some practical insights on how a scientific research team might incorporate a strong and effective ELSI program within its broader research mandate. We begin by describing the historical context of ELSI research and the development of GE3LS research in the Canadian context. We then illustrate how some ELSI research might unfold by outlining a variety of GE3LS research questions or content domains and the methodologies that might be employed in studying them. We conclude with some practical suggestions about how to build an effective ELSI/GE3LS team and focus within a broader scientific research program.

Abstract
The current study was designed to evaluate the attitude of the Saudi general population towards knowledge, perception and awareness about genetic testing. Using a convenience sampling technique, an online survey was used to collect the data. The survey consisted of 16 questions that covered basic demographics and several scenarios that assess subjects’ perceptions regarding genetic testing. Answering all questions was required for completing the survey. Among 333 subjects, 53.5% were male, 18.9% were married, and 99.4% were muslims. Around 75% has/will have a bachelor degree. About 59% were students. About 87% would consider genetic testing before marriage and similar percentage would not consider conceiving a child if the genetic screening indicated that there is 100% chance the child will be born with genetic disorder. Neither marital status (Single = 87.04%, married = 87.30% (P = 0.955)) nor gender (male = 85.96, female = 88.39 (P = 0.509)) affected the aforementioned decision. When subjects were asked if they would choose abortion knowing that the embryo has a severe genetic disorder, 62.7% answered yes. In general, 80.4% were willing to be recruited into a genetics study, married subjects were more reluctant to be recruited compared to singles (30% and 17% (P = 0.018) respectively). There was no difference between males and females in the decision of joining a genetic study. Also 78.4% supported creation of genetic disease database and family maps. 69.7% of the participants supported government enforcement of the genetic testing, 56.2% supported government-run facilities for Saudi citizens to have genetic tests. We conclude that married people were in favor of genetic testing than the single counterparts, secondly, single status people supported the idea of having genetic tests before their marriage they were supportive of the idea of the government taking a leading role in enforcing the genetic testing and creation of the genetic banks.

Abstract
Aim: Direct-to-consumer (DTC) genetic tests (GT) have created controversy regarding their risks and benefits. In view of recent regulatory developments, this article aims to explore the attitudes of European clinical geneticists toward the oversight of DTC GT. Materials & methods: Fifteen semi-structured interviews were performed with clinical geneticists based in ten European countries. The transcripts were thematically analysized in an iterative process. Results & conclusion: Respondents strongly supported quality standards for DTC GT equal to those applied within the healthcare setting. Despite participants unanimously considering the involvement of healthcare professionals to be important, mandatory medical supervision was controversial. In this regard, promoting education and truth-in-advertising was considered as being key in maintaining a balance between protecting consumers and promoting their autonomy.

Abstract
The direct-to-consumer genetic testing (DTC-GT) market has been developing for about twenty years now, raising various debates, even controversies. But what about the regulation of these so-called "innovative" devices, but whose medical status is ambiguous? A first regulatory aspect is depending on the market itself, since the latter is currently subjected to a strong structuring process. A second regulatory aspect, more classical, is the legal one. While the DTC-GT status has long been unclear on European scale, a new text (a Regulation, not a Directive) is modifying the situation. It encourages regulation "by the market" rather than "by the medical profession", which does not imply that the latter will have no (indirect) impact on the DTC-GT market.

Abstract
Background Recent progress in genome data collection and analysis technologies has led to a surge of direct-to-consumer (DTC) genetic testing services. Owing to the clinical value and sensitivity of genomic data, as well as uncertainty and hearsay surrounding business practices of DTC genetic testing service providers, DTC genetic testing has faced significant criticism by researchers and practitioners. Research in this area has centered on ethical and legal implications of providing genetic tests directly to consumers, but we still lack a more profound understanding of how businesses in the DTC genetic testing markets work and provide value to different stakeholders. Objective The aim of this study was to address the lack of knowledge concerning business models of DTC genetic testing services by systematically identifying the salient properties of various DTC genetic testing service business models as well as discerning dominant business models in the market. Methods We employed a 3-phased research approach. In phase 1, we set up a database of 277 DTC genetic testing services. In phase 2, we drew on these data as well as conceptual models of DTC genetic testing services and iteratively developed a taxonomy of DTC genetic testing service business models. In phase 3, we used a 2-stage clustering method to cluster the 277 services that we identified during phase 1 and derived 6 dominant archetypes of DTC genetic testing service business models. Results The contributions of this research are 2-fold. First, we provided a first of its kind, systematically developed taxonomy of DTC genetic testing service business models consisting of 15 dimensions in 4 categories. Each dimension comprises 2 to 5 characteristics and captures relevant aspects of DTC genetic testing service business models. Second, we derived 6 archetypes of DTC genetic testing service business models named as follows: (1) low-cost DTC genomics for enthusiasts, (2) high-privacy DTC genomics for enthusiasts, (3) specific information tests, (4) simple health tests, (5) basic low-value DTC genomics, and (6) comprehensive tests and low data processing. Conclusions Our analysis paints a much more complex business landscape in the DTC genetic testing market than previously anticipated. This calls for further research on business models and their effects that underlie DTC genetic testing services and invites specific regulatory interventions to protect consumers and level the playing field.

Abstract
Background: Personal genomic testing (PGT) offers individuals genetic information about relationships, wellness, sporting ability, and health. PGT is increasingly accessible online, including in emerging markets such as Australia. Little is known about what consumers expect from these tests and whether their reflections on testing resonate with bioethics concepts such as autonomy.Methods: We report findings from focus groups and semi-structured interviews that explored attitudes to and experiences of PGT. Focus group participants had little experience with PGT, while interview participants had undergone testing. Recordings were transcribed and analyzed using thematic analysis. Findings were critically interpreted with reference to bioethics scholarship on autonomy.Results: Fifty-six members of the public participated in seven focus groups, and 40 individuals were interviewed separately. Both groups valued the choice of PGT, and believed that it could motivate relevant actions. Focus group themes centered on the perceived value of choices, knowledge enabling action and knowledge about the self. Interview themes suggest that participants reflexively engage with their PGT information to make meaning, and that some appreciate its shortcomings. Critical interpretation of findings shows that while consumers of PGT are able to exercise a degree of autonomy in choosing, they may not be able to achieve a substantive conceptualization of autonomy, one that promotes alignment with higher-order desires.Conclusions: PGT consumers can critically reason about testing. However, they may uncritically accept test results, may not appreciate drawbacks of increased choice, or may overestimate the potential for information to motivate behavioral change. While consumers appear to be capable of substantive autonomy, they do so without ongoing support from companies. PGT companies promote a problematic ("default") account of autonomy, reliant on empowerment rhetoric. This leaves consumers vulnerable to making decisions inconsistent with their higher-order desires. As PGT expands, claims about its power and value need to be carefully drawn.

Abstract
The growth in the direct-to-consumer genetic testing industry poses a number of challenges for healthcare practice, among a number of other areas of concern. Several companies providing this service send their customers reports including information variously referred to as genetic ethnicity, genetic heritage, biogeographic ancestry, and genetic ancestry. In this article, we argue that such information should not be used in healthcare consultations or to assess health risks. Far from representing a move toward personalized medicine, use of this information poses risks both to patients as individuals and to racialized ethnic groups because of the way it misrepresents human genetic diversity.

Abstract
Personal genomic tests (PGTs) for multiple purposes are marketed to ostensibly healthy people in Australia. These tests are generally marketed and purchased online commercially or can be ordered through a health professional. There has been minimal engagement with Australians about their interest in and experience with ordering a PGT. As part of a multistage, interdisciplinary project, an online survey (Stage 2 of the Genioz study) was available from May 2016 to May 2017. In total, 3253 respondents attempted the survey, with 2395 completed Australian responses from people with and without experience of having a PGT: 72% were female; 59% of the whole sample were undertaking/or had a university education; and, overall, age ranged from 18—over 80. A total of 571 respondents reported having had a genetic test, 373 of these classifiable as a PGT. A bivariate analysis suggests people who have undergone PGT in our sample were: women aged 25 and over; or in a high socioeconomic group, or have a personal or family diagnosis of a genetic condition (P ≤ 0.03). After a multivariate analysis, socioeconomic status and a genetic condition in the family were not of significance. The most common types of PGT reported were for carrier status and ancestry. Findings suggest greater awareness of, and an increasing demand for non-health related PGT in Australia. To support both consumers and health care professionals with understanding PGT results, there is a need for appropriate support and resources.

Abstract
Genetic ancestry testing (GAT) is marketed as a way to make up for missing knowledge about one's ancestry. Previous research questions the GAT industry's ability to fulfill this promise in terms of the validity and reliability of test results. We instead explore the demand side of GAT, evaluating who is most and least likely to express interest in GAT. Using data from an original, nationwide survey of over 100,000 American adults, we find that GAT interest is related to both self-identified race and immigrant generation, with Asian Americans and first-generation immigrants expressing the least interest. Our quantitative and qualitative evidence suggests interest is further shaped by a pre-existing sense of ancestral certainty, leading some individuals to decline GAT, even if it were free. How interest and ancestral certainty are patterned has implications for who is included in - and thus for the conclusions that can be drawn from - genetic ancestry databases.

Abstract
This study reports on 13 semistructured in-depth interviews to qualitatively explore the experiences of individuals who publicly shared their direct-to-consumer genetic testing results on the platform openSNP. In particular, we focused on interviewees' understanding of privacy. Participants reported that the likelihood and the magnitude of privacy harms depend on gender, ethnicity, sexual orientation, the stigma associated with certain clinical conditions, the existence of adequate legislation, and the nature of national health care systems. Some participants expressed the view that those who enjoy higher socioeconomic status or are better protected by their country's legislation have a responsibility to share their genetic data. Our study shows that people who share their genetic data publicly online-far from being insensitive to privacy risks-have a complex understanding of the social, relational, and contextual nature of genetic privacy.

Abstract
BACKGROUND Increasing evidence is demonstrating that a patient's unique genetic profile can be used to detect the disease's onset, prevent its progression, and optimize its treatment. This led to the increased global efforts to implement personalized medicine (PM) and pharmacogenomics (PG) in clinical practice. Here we investigated the perceptions of students from different universities in Bosnia and Herzegovina (BH) towards PG/PM as well as related ethical, legal, and social implications (ELSI). This descriptive, cross-sectional study is based on the survey of 559 students from the Faculties of Medicine, Pharmacy, Health Studies, Genetics, and Bioengineering and other study programs. RESULTS Our results showed that 50% of students heard about personal genome testing companies and 69% consider having a genetic test done. A majority of students (57%) agreed that PM represents a promising healthcare model, and 40% of students agreed that their study program is well designed for understanding PG/PM. This latter opinion seems to be particularly influenced by the field of study (7.23, CI 1.99-26.2, p = 0.003). Students with this opinion are also more willing to continue their postgraduate education in the PM (OR = 4.68, CI 2.59-8.47, p < 0.001). Furthermore, 45% of students are aware of different ethical aspects of genetic testing, with most of them (46%) being concerned about the patient's privacy. CONCLUSIONS Our results indicate a positive attitude of biomedical students in Bosnia and Herzegovina towards genetic testing and personalized medicine. Importantly, our results emphasize the key importance of pharmacogenomic education for more efficient translation of precision medicine into clinical practice.

Abstract
A Dutch university hospital started offering cystic fibrosis (CF) carrier screening directly to consumers (DTC) through their website in 2010. A 6-year process evaluation was conducted to evaluate the offer. Screening was implemented as intended. However, uptake was lower than expected. Forty-four tests have been requested, partly by couples with a positive family history for CF, which was not the intended target group. Users were generally positive about the screening offer, citing accessibility, ease of testing, anonymity, and perceived shortcomings of regular healthcare as reasons for requesting screening. DTC CF carrier screening via a university hospital website is feasible, but is seldom used. Considering technological advances, continuation of this specific offer is questionable.

Abstract
Direct to consumer (DTC) genetic testing has given rise to much controversy, especially in relation to testing for health diagnostic purposes. This paper will consider whether consumers' use of DTC genetic testing should be understood as predominantly recreational. It will be argued that recreational testing can encompass all information domains, including most kinds of predictive health risk information. In relation to recreational testing the potential identity implications for the consumer become a significant concern, more so than the risks more traditionally associated with genetic testing. It will be concluded that while the DTC genetic testing sector is beset by numerous problems and an increase in consumers' genetic literacy is highly desirable, consumers' engagement with DTC genetic testing may be less problematic than sometimes assumed.

Abstract
Cancer-related genetic and genomic testing (CGT) is changing cancer care by personalizing care options, leading to an era of precision medicine. Advances in and increased use of CGT add complexity to clinical communication. This landscape analysis assessed published reviews of communication issues related to CGT and discusses implications for practice and behavioral research. A comprehensive electronic literature search was conducted of peer-reviewed literature reviews on studies related to CGT communication published between January 2010 and January 2017, resulting in a final sample of 24 reviews. Reviews were categorized, with overlaps, into four domains across the genetic testing communication continuum. Reviews on CGT-related knowledge, attitudes, and perceptions (n = 8) found that despite substantial public interest, their knowledge and awareness remains low. Providers also reported insufficient knowledge and overall caution, particularly regarding direct-to-consumer (DTC) genetic testing. Reviews of decision-making about CGT and test uptake (n = 8) identified individual, interpersonal, and systems-level barriers to uptake. Reviews of patient-provider CGT communication (n = 8) revealed limited communication and little empirical research on outcomes of communication or efforts at improving clinical and family communication. There were mixed findings in reviews (n = 15) on the psychological and behavioral impact of CGT, and DTC testing particularly had little effect on behaviors. Taken together, there is very little extant research in CGT in minority and underserved communities. In order for scientific advances in CGT to translate into equitable, patient-centered care, behavioral research, including health literacy and communication, plays critical roles.

Abstract
OBJECTIVES It is unclear whether family medical history influences the willingness to undergo genetic testing. This study aimed to determine how family history affected the willingness to undergo genetic testing for salt-sensitive hypertension in patients with and without hypertension. DESIGN Cross-sectional study using a self-administered questionnaire. SETTING Six primary care clinics and hospitals in Japan. PARTICIPANTS Consecutive 1705 outpatients aged >20 years, 578 of whom had hypertension. PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome variable was the willingness to undergo genetic testing to determine the risk of salt-sensitive hypertension, and the secondary variables were age, sex, education level, family history and concerns about hypertension. Factors associated with a willingness to undergo genetic testing were evaluated in patients with and without hypertension using a logistic regression model. RESULTS In the hypertension and non-hypertension groups, 323 (55.9%) and 509 patients (45.2%), respectively, were willing to undergo genetic testing. This willingness was related with a high level of education (adjusted OR (ad-OR): 1.81, 95% CI 1.12 to 2.93), family history of stroke (1.55, 1.04 to 2.31) and concerns about hypertension (2.04, 1.27 to 3.28) in the hypertension group, whereas in the non-hypertension group, it was influenced by education level (ad-OR: 1.45, 95% CI 1.13 to 1.86), family history of hypertension (1.52, 1.17 to 1.98) and concerns about hypertension (2.03, 1.53 to 2.68). CONCLUSIONS The influence of family history on the willingness to undergo genetic testing for risk of salt-sensitivity hypertension differed between participants with and without hypertension. In particular, participants without hypertension wished to know their likelihood of developing hypertension, whereas those with hypertension were interested to know the risk of stroke (a complication of hypertension). Family history could help better counsel patients about genetic testing on the basis of their medical history.

Abstract
Websites from medical specialist providers are becoming increasingly marketing oriented, but there exists a paucity of empirical research on the effects. This experimental study explored effects of exposure to real websites from medical specialist providers among Dutch adults under physician gatekeeper arrangements. Exposure led to a stronger intention to seek treatment from the specialist provider and motivation to rely on the providers' claims. Weaker to absent effects were found for intention to question the physician gatekeeper's referral and this was chiefly motivated by the belief that "the doctor knows best." Implications for specialist provider marketing under gatekeeping arrangements are discussed.

Abstract
Background Direct-to-consumer genetic tests (DTC-GT) are easily purchased through the Internet, independent of a physician referral or approval for testing, allowing the retrieval of genetic information outside the clinical context. There is a broad debate about the testing validity, their impact on individuals, and what people know and perceive about them. Objective The aim of this review was to collect evidence on DTC-GT from a comprehensive perspective that unravels the complexity of the phenomenon. Methods A systematic search was carried out through PubMed, Web of Knowledge, and Embase, in addition to Google Scholar according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist with the key term “Direct-to-consumer genetic test.” Results In the final sample, 118 articles were identified. Articles were summarized in five categories according to their focus on (1) knowledge of, attitude toward use of, and perception of DTC-GT (n=37), (2) the impact of genetic risk information on users (n=37), (3) the opinion of health professionals (n=20), (4) the content of websites selling DTC-GT (n=16), and (5) the scientific evidence and clinical utility of the tests (n=14). Most of the articles analyzed the attitude, knowledge, and perception of DTC-GT, highlighting an interest in using DTC-GT, along with the need for a health care professional to help interpret the results. The articles investigating the content analysis of the websites selling these tests are in agreement that the information provided by the companies about genetic testing is not completely comprehensive for the consumer. Given that risk information can modify consumers’ health behavior, there are surprisingly few studies carried out on actual consumers and they do not confirm the overall concerns on the possible impact of DTC-GT. Data from studies that investigate the quality of the tests offered confirm that they are not informative, have little predictive power, and do not measure genetic risk appropriately. Conclusions The impact of DTC-GT on consumers’ health perceptions and behaviors is an emerging concern. However, negative effects on consumers or health benefits have yet to be observed. Nevertheless, since the online market of DTC-GT is expected to grow, it is important to remain aware of a possible impact.

Abstract
The success of personalised medicine depends upon the public's embracing genetic tests. Tests that claim to predict an individual's future health can now be accessed via online companies outside of conventional health regulations. This research assessed the extent to which the public embrace direct-to-consumer (DTC) genetic tests relative to those obtained by a conventional medical practitioner (MP). It also examined the reasons for differences across providers using a randomised experimental telephone survey of 1000 Australians. Results suggest that people were significantly less likely to approve of, and order a DTC genetic test administered by a company compared to a MP because they were less trusting of companies' being able to protect their privacy and provide them with access to genetic expertise and counselling. Markets for DTC genetic tests provided by companies would therefore significantly increase if trust in privacy protection and access to expertise are enhanced through regulation.

Abstract
In 1995, the American Society of Human Genetics (ASHG) and American College of Medical Genetics and Genomics (ACMG) jointly published a statement on genetic testing in children and adolescents. In the past 20 years, much has changed in the field of genetics, including the development of powerful new technologies, new data from genetic research on children and adolescents, and substantial clinical experience. This statement represents current opinion by the ASHG on the ethical, legal, and social issues concerning genetic testing in children. These recommendations are relevant to families, clinicians, and investigators. After a brief review of the 1995 statement and major changes in genetic technologies in recent years, this statement offers points to consider on a broad range of test technologies and their applications in clinical medicine and research. Recommendations are also made for record and communication issues in this domain and for professional education.

Abstract
Direct to consumer genetic testing offered via the Internet has been available for over a decade. Initially most tests of this type were offered without the input of the consumer's own health professional. Ethical and practical concerns have been a raised over the use of such tests: these include fulfilling the requirement for informed consent, utility of results for health care management and the potential burden placed upon health services by people who have taken tests.These tests now have an application in reproductive healthcare. The advent of non-invasive prenatal testing has facilitated the genetic testing of the fetus using only a maternal blood sample. However, companies offering such tests, for example for aneuploidy, appear to be doing so based on a referral from the mother's health professional. Preconception or prenatal carrier testing for a range of autosomal recessive conditions can be purchased without the input of a health professional who knows the prospective parents. However, unless the appropriate mutations for the specific population are included in the test, results may create false reassurance. Paternity testing without the consent of the putative father is also available via the Internet, as are tests to ascertain the sex of the fetus, which may be used to select children of a specific gender.Direct-to-consumer tests may support prospective parents to identify genetic risk to their future children, however, it is important that they are aware of the possible limitations, as well as advantages, of these tests. National regulation may not prove effective in ensuring the safety of all individuals involved, therefore international pressure to ensure companies conform to Codes of Practice may be needed, especially in relation to tests that could influence reproductive decisions. However, health professionals have a duty to ensure they are sufficiently knowledgeable to enable them to guide patients appropriately.

Abstract
Background: An increasing number of direct-to-consumer (DTC) genetic testing companies have started offering tests for carrier status of autosomal recessive disorders. Materials & Methods: A written questionnaire was administered to 47 patients and 65 parents of children with Cystic Fibrosis (CF), a common severe autosomal recessive disorder, to assess their views about the offer of DTC carrier tests. All participants were recruited from a CF patient registry in Belgium. Results & Conclusion: We found that very few patients and parents were aware of the offer of DTC genetic testing for carrier status, and were generally skeptical. A strong preference for the healthcare system over commercial companies as the provider of the test was observed. However, many participants believe people should have a right to access DTC genetic tests provided by commercial companies.

Abstract
ELSI (Ethical, Legal, and Social Issues) is a widely used acronym in the bioethics literature that encompasses a broad range of research areas involved in examining the various impacts of science and technology on society. In Canada, GE3LS (Genetics, Ethical, Economic, Environmental, Legal, Social issues) is the term used to describe ELSI studies. It is intentionally more expansive in that GE3LS explicitly brings economic and environmental issues under its purview. ELSI/GE3LS research has become increasingly important in recent years as there has been a greater emphasis on "translational research" that moves genomics from the bench to the clinic. The purpose of this chapter is to outline a range of ELSI-related work that might be conducted as part of a large scale genetics or genomics research project, and to provide some practical insights on how a scientific research team might incorporate a strong and effective ELSI program within its broader research mandate. We begin by describing the historical context of ELSI research and the development of GE3LS research in the Canadian context. We then illustrate how some ELSI research might unfold by outlining a variety of research questions and the various methodologies that might be employed in addressing them in an area of ELSI research that is encompassed under the term "public engagement." We conclude with some practical pointers about how to build an effective ELSI/GE3LS team and focus within a broader scientific research program.

Abstract
The considerable advances of genome sequencing over the past decades have had a profound impact on our daily life and opened up new avenues for the public to have access to their genetic information and learn more about their ancestry, genealogy and other traits that make each of us unique individuals. A very large number of individual single nucleotide polymorphisms (SNPs) have been associated to diseases whereas others have no known phenotype. For example, among the SNPs mapped within ccn1(cyr61), ccn2(ctgf), ccn3(nov), ccn4(wisp-1), ccn5(wisp-2) and ccn6 (wisp-3), only mutations within ccn4 were associated to PPD (the autosomal recessive skeletal disorder Progressive Pseudorheumatoid Dysplasia). On the occasion of this JCCS special issue on the roles of hormetic responses in adaptation, and response of living species to the modifications of their environment, it appeared that it was a good time to briefly review a topic that has been the subject of passionate discussions for the past few years, that is Direct to Consumer genetic tests (DTC GT). Based on the use of DNA analysis and identification of polymorphisms, DTC GT have been developed by several companies in the USA and in countries where there was no legal obstacle for customers to have direct access to their genetic information and manage their healthcare. Problems that arose and decisions that have been taken by regulatory agencies are presented and discussed in this editorial. The « freeze » of health-oriented DTC GT in the USA neither implies the end of DNA analysis nor « fun » applications, which are not aimed at providing risks estimates for particular illnesses. As shown in the example which is discussed in this editorial, DTC GT for cosmetic applications might be considered a fun application of great interest for companies such as L'Oréal, who recently developed the Makeup Genius mobile application. Other fun applications of DTC GT are discussed but there is no doubt that nothing will stop progress and it is most probable than within a few years from now all the tensions raised about these procedures will vanish to the profit and benefit of consumers. In any case, this will only be possible through an intensive communication effort, because …communication is the key !

Gatekeepers or intermediaries? The role of clinicians in commercial genomic testing. PLoS One 2014; 9:e108484.

Abstract
Background Many commentators on “direct-to-consumer” genetic risk information have raised concerns that giving results to individuals with insufficient knowledge and training in genomics may harm consumers, the health care system, and society. In response, several commercial laboratories offering genomic risk profiling have shifted to more traditional “direct-to-provider” (DTP) marketing strategies, repositioning clinicians as the intended recipients of advertising of laboratory services and as gatekeepers to personal genomic information. Increasing popularity of next generation sequencing puts a premium on ensuring that those who are charged with interpreting, translating, communicating and managing commercial genomic risk information are appropriately equipped for the job. To shed light on their gatekeeping role, we conducted a study to assess how and why early clinical users of genomic risk assessment incorporate these tools in their clinical practices and how they interpret genomic information for their patients. Methods and Findings We conducted qualitative in-depth interviews with 18 clinicians providing genomic risk assessment services to their patients in partnership with DNA Direct and Navigenics. Our findings suggest that clinicians learned most of what they knew about genomics directly from the commercial laboratories. Clinicians rely on the expertise of the commercial laboratories without the ability to critically evaluate the knowledge or assess risks. Conclusions DTP service delivery model cannot guarantee that providers will have adequate expertise or sound clinical judgment. Even if clinicians want greater genomic knowledge, the current market structure is unlikely to build the independent substantive expertise of clinicians, but rather promote its continued outsourcing. Because commercial laboratories have the most “skin in the game” financially, genetics professionals and policymakers should scrutinize the scientific validity and clinical soundness of the process by which these laboratories interpret their findings to assess whether self-interested commercial sources are the most appropriate entities for gate-keeping genomic interpretation.

Abstract
Developments in genomics continue to increase the number of disorders for which genetic testing is available, whether in the primary healthcare system, through direct-to-consumer testing, or as part of expanded newborn screening panels. This paper reviews a robust literature on public attitudes toward genetics and genetic testing. In general, attitudes are positive about genetic research and new genomic technologies, with majorities indicating an interest in genetic testing. However, complex beliefs comprise the public's thinking about genetics. Attitudes are driven by beliefs about the type of genetic research, the personal and clinical utility of tests, and the area of genetics in which testing is applied. Limitations of current research are noted and suggestions made for future research.

Abstract
BACKGROUND Direct-to-consumer (DTC) genetic tests are available online, but there is little practical guidance for health professionals and consumers concerning their use. Work to produce such guidance was initially informed by three systematic reviews assessing the evidence on views and experiences of users and health professionals and policies of professional and bioethics organizations. The evidence suggested that consumers' motivations include general curiosity, improving their general health, ascertaining the risk of a particular condition or planning for future children. However, health professionals and bioethics organizations expressed concerns about potential harms resulting from these tests. Using this evidence, we constructed a list of topics to be included in proposed guidelines. METHODS Using an expert group technique, we aimed to develop guidance for (i) potential consumers and (ii) health professionals approached by patients considering or having undertaken such tests. We considered it important to involve a wide range of participants with relevant experience. Accordingly, researchers and clinicians based in four countries were invited to a 2-day workshop in August 2012. Following an iterative process, we decided to produce clinically relevant and pragmatic guidance in the form of a decision support tool for use in primary care. RESULTS By utilizing both the relevant literature and the experience of the expert group, we identified seven key underlying reasons that might prompt individuals to consider DTC testing. We considered primary care physicians as the most likely health professionals from whom individuals would seek advice. CONCLUSIONS Based on the outcomes of the workshop, we developed a decision support tool encompassing varied clinical scenarios. Health professionals and patients are guided through a pathway that includes relevant actions and information on the appropriateness of the test. This tool will be freely accessible to health professionals and patients online.

Abstract
With the costs of genomic and genetic testing rapidly decreasing, private companies have begun to offer consumers, including minors, the opportunity to receive a genetic analysis of their DNA. The availability of direct-to-consumer genetic testing (DTC-GT) will inevitably result in patients approaching their healthcare providers for interpretation of results, referrals for follow-up tests or provision of personalized medicine. As most healthcare systems require a referral for access to a specialist, the patients are likely to approach primary care providers. The issue of what the professional obligations are for the primary care physician in the case where they did not order the test is not new. The growing DTC-GT movement will add a 'new twist to an old problem.' Best practice recommendations regarding the value of DTC-GT, as well as the identification of current ethical, legal and social implications are urgently needed.

Abstract
Background The current research into single nucleotide polymorphisms has extended the role of genetic testing to the identification of increased risk for common medical conditions. Advances in genetic research may soon necessitate preparation for the role of genetic testing in primary care medicine. This study attempts to determine what proportion of patients would be willing to undergo genetic testing for salt-sensitive hypertension in a primary care setting, and what factors are related to this willingness. Methods A cross-sectional study using a self-report questionnaire was conducted among outpatients in primary care clinics and hospitals in Japan. The main characteristics measured were education level, family medical history, personal medical history, concern about hypertension, salt preference, reducing salt intake, and willingness to undergo genetic testing for salt-sensitive hypertension. Results Of 1,932 potential participants, 1,457 (75%) responded to the survey. Of the respondents, 726 (50%) indicated a willingness to undergo genetic testing. Factors related to this willingness were being over 50 years old (adjusted odds ratio [ad-OR] = 1.42, 95% Confidence interval = 1.09 – 1.85), having a high level of education (ad-OR: 1.83, 1.38 – 2.42), having a family history of hypertension (ad-OR: 1.36, 1.09 – 1.71), and worrying about hypertension (ad-OR: 2.06, 1.59 – 2.68). Conclusions Half of the primary care outpatients surveyed in this study wanted to know their genetic risk for salt-sensitive hypertension. Those who were worried about hypertension or had a family history of hypertension were more likely to be interested in getting tested. These findings suggest that primary care physicians should provide patients with advice on genetic testing, as well as address their anxieties and concerns related to developing hypertension.

Abstract
BACKGROUND Genetic testing and family history assessment can be used as an aid in the prevention of common chronic diseases. The aim of this study was to determine public attitudes and interests towards offering genetic testing and family history-based risk assessment for common chronic disease prevention. METHODS Cross-sectional questionnaire survey of a consumer panel representative for the Dutch population. The questionnaire was sent to 1399 panel members, aged ≥ 18 years. RESULTS The response was 70% (978/1399). About half of the respondents expressed an interest in genetic testing to prevent specific diseases (cancer, cardiovascular disease, diabetes or dementia), with lower-educated respondents showing more interest than higher-educated respondents. Few respondents (24%) agreed that people should be preventively tested for all kinds of diseases. According to the respondents, genetic testing should be performed in the hospital (66%) and be directed to curable (57%) or preventable diseases (69%). Half of the respondents believed that family history assessment could help prevent disease, but only 21% thought it should be offered to everyone, as this could cause people to be worried. A minority (12%) reported that their family history had been assessed, whereas 59% did not have it assessed and did not think this would be necessary. Respondents have differentiated interests in preventive genomics, which varies depending on sex, age and level of education. CONCLUSIONS Members of the public are interested in genetic testing for preventable and curable diseases, but they are ambivalent about family history risk assessment to prevent disease.

Abstract
Little is known about the decisions and perspectives of participants undergoing direct-to-consumer genetic testing (DTCGT). The aims of this study were to examine the views, attitudes and decision-making factors of primary care patients regarding DTCGT. Their experience of and reactions to testing also emerged during the study. In this longitudinal, qualitative study, 20 primary care patients participated in DTCGT and individual interviews: (1) prior to testing after the informed consent session, (2) after receiving results, (3) 3 months post-test, and (4) 12 months post-test. Interviews included open-ended questions and all transcripts were analyzed using grounded theory, constant comparison methods. Five key themes emerged from data analysis as participants underwent DTCGT and reflected on their decision over time: (1) limited concerns about DTCGT, (2) motivations for testing, (3) expectations of testing, (4) understanding of results, and (5) impact of testing and results. While a few participants expressed concerns before testing, participants were motivated to test by curiosity, gaining actionable knowledge, and altruism. Most were uncertain of what to expect from DTCGT and needed assistance in understanding results. While many reported testing had no significant impact on them, being relieved or pleased after testing was the most common emotional effect. Notably, a few participants made positive health changes in response to testing. Given the paucity of information about primary care patients and DTCGT, this study adds more in-depth information to the emerging research on how such participants' view, make decisions about, experience and react to DTCGT over time. Because uncertainty remains about the accuracy of DTCGT, the response of primary care patients to this testing requires further investigation.

Abstract
The last several years has witnessed an explosion in genomics, with the advent of genome-wide association studies revealing hundreds of DNA variants significantly associated with most common diseases, including cancer. On the heels of these scientific advances came the direct-to-consumer (DTC) genetic testing industry. Genome-wide scans for disease have been marketed and sold directly to the public, without the involvement of a health care provider. Unlike genetic testing for mutations in known hereditary cancer susceptibility genes such as BRCA1/2, these genomic profiles examine DNA variants, which typically have a minimal risk impact, and account for only a fraction of the heritable component of cancer. Furthermore, risk information provided to consumers does not account for family history or other known risk factors. The clinical validity and utility of personal genome scans for disease risk prediction remain for the most part unestablished, although some argue lack of evidence of harm and the possibility that positive impacts on health behaviors or genetic awareness may result from consumer use. The DTC genetic testing industry has sparked significant controversy not only among the scientific community, but also among professional societies and government agencies.In this review, we present some of the history and methodological considerations of DTC genomic profiling, with a focus on cancer risk prediction. The literature regarding consumer awareness and utilization is explored, including understanding, expectations, and behavioral and psychological responses to DTC genomic risk prediction. Primary care provider and genetic professional knowledge and perceptions of DTC genomic profiling are also addressed. Ethical and scientific controversy surrounding the DTC genetic testing industry is presented, along with policy recommendations, regulatory actions, and the changing landscape of the DTC genetic testing market in response. Although our understanding of the human genome holds much promise in the realm of cancer prevention and treatment, DTC genomic profiling for cancer risk prediction is unlikely in its current form to have any significant impact on the health of the public. Time will tell if the next venture in genomic medicine, whole genome sequencing, will be accompanied by the translational research and emphasis on public/provider education required to ensure its successful application toward reducing the burden of cancer at a population level.

Abstract
Ten years after the Human Genome Project, medicine is still waiting for many of the promised benefits, and experts have tempered their high expectations. Public opinion on genetic testing has generally been favourable but is this still the case? The aim of this study is to compare public experiences, beliefs and expectations concerning genetic testing over the years (2002 vs 2010). A cross-sectional questionnaire survey was conducted using the Dutch Health Care Consumer Panel in 2002 and 2010. Responses to questions in identical wording were compared. In 2002 and 2010, 817 (63%) and 978 (70%) members responded, respectively. Awareness and reported use of genetic tests remained stable over time. In 2010, more respondents expected genetic testing to become more widely applied, believed that knowledge about the genetic background of disease helps people live longer, and that testing should be promoted more intensively. In 2010, they were also more interested in their own genetic make-up. On the one hand, the concern that a dichotomy would emerge between people with 'good genes' and 'bad genes' was higher. On the other hand, respondents thought that insurance companies would be less likely to demand a genetic test in order to calculate health insurance premiums. In conclusion, the results suggest that in 8 years, expectations of benefits and potential use of genetic testing have been raised among the public, resulting in more positive opinions. Worries on inequity remain, although worries about premium differentiation by insurance companies have decreased.

Indeed, discoveries into the genomic basis of cancer and other common chronic diseases have resulted in new and improved predictive tests for identifying individuals at increased risk for these conditions and long before their onset occurs. When used properly, information gained from predictive genomic tests can be combined with other leading indicators (e.g., environmental and behavioral risk factors) to inform medical management decisions, preventive health practices, and risk-reducing strategies. However, genomics remains an emerging science and the translation of genomic discoveries into improved population health management remains elusive. There are divides in the translational science continuum at several junctures, and many of these divides could be narrowed or closed with additional data. For example, we know relatively little about how to effectively communicate with the public about the complex interplay among genomics, behavior, and health. Moreover, there is a need to develop better methods of counseling and educating the public in light of newly emerging knowledge about the genomic basis of health and disease. We assert that the discipline of psychology, and health psychology in particular, is well-poised to continue to make significant contributions to this growing area of science and practice. Through a focus on health-related social and behavioral research, psychology can lead the way in overcoming divides in communication, understanding, and action about genomics for the betterment of both individual and public health practices.

Abstract
This article reviews recent developments in health care law, focusing on controversy at the intersection of health care law and culture. The article addresses: emerging issues in federal regulatory oversight of the rapidly developing market in direct-to-consumer genetic testing, including questions about the role of government oversight and professional mediation of consumer choice; continuing controversies surrounding stem cell research and therapies and the implications of these controversies for healthcare institutions; a controversy in India arising at the intersection of abortion law and the rights of the disabled but implicating a broader set of cross-cultural issues; and the education of U.S. health care providers and lawyers in the theory and practice of cultural competency.

"Is it really worth it to get tested?": primary care patients' impressions of predictive SNP testing for colon cancer. J Genet Couns 2012; 22:138-51. [PMID: 22911325 DOI: 10.1007/s10897-012-9530-x] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2011] [Accepted: 07/18/2012] [Indexed: 12/26/2022]
Abstract
Despite significant progress in genomics research over the past decade, we remain years away from the integration of genomics into routine clinical care. As an initial step toward the implementation of genomic-based medicine, we explored primary care patients' ideas about genomic testing for common complex diseases to help develop future patient education materials and interventions to communicate genomic risk information. We conducted a mixed-methods study with participants from a large primary care clinic. Within four focus groups, we used a semi-structured discussion guide and administered brief pre- and post- discussion quantitative surveys to assess participants' interest, attitudes, and preferences related to testing and receipt of test results. Prior to the discussion, moderators presented a plain-language explanation of DNA and genetics, defined "SNP", and highlighted what is known and unknown about the risks associated with testing for SNPs related to colorectal cancer risk. We used the NVIVO 8 software package to analyze the transcripts from the focus group discussions. The majority of participants (75 %) were "very" or "somewhat interested" in receiving information from a colon cancer SNP test, even after learning about and discussing the small and still clinically uncertain change in risk conferred by SNPs. Reported interest in testing was related to degree of risk conferred, personal risk factors, family history, possible implications for managing health /disease prevention and curiosity about genetic results. Most people (85 %) preferred that genetic information be delivered in person by a healthcare or genetics professional rather than through print materials or a computer. These findings suggest that patients may look to genetic counselors, physicians or other healthcare professionals as gatekeepers of predictive genomic risk information.

Abstract
Although single nucleotide polymorphism (SNP) testing for disease susceptibility is commercially available, translational studies are necessary to understand how to communicate genomic information and potential implications for public health. We explored attitudes about and initial responses to genomic testing for colon cancer risk. Following development of the educational materials, we offered testing for three colon cancer SNPs in a pilot study with primary care patients. Participants completed pre- and post-test sessions and interviews. We analyzed interview transcripts with qualitative software using thematic analysis. All 20 participants opted for SNP testing. Qualitative analysis identified several themes: Motivations for SNP Testing, Before/After: Meaning of Results, Emotional Responses to SNP Results and Genomic Literacy/ Information Delivery. Results demonstrate that individuals will pursue SNP testing in the context of pre and post-test education. SNP results may influence health behaviors like healthy eating and exercise yet did not appear to impact colon cancer screening intentions.
