Ethical, Legal, and Social Issues (ELSI) in Clinical Genetics Research

Understanding and applying gene-environment interactions: a guide for nutrition professionals with an emphasis on integration in African research settings

Noncommunicable diseases (NCDs) are influenced by the interplay between genetics and environmental exposures, particularly diet. However, many healthcare professionals, including nutritionists and dietitians, have limited genetic background and, therefore, they may lack understanding of gene-environment interactions (GxEs) studies. Even researchers deeply involved in nutrition studies, but with a focus elsewhere, can struggle to interpret, evaluate, and conduct GxE studies. There is an urgent need to study African populations that bear a heavy burden of NCDs, demonstrate unique genetic variability, and have cultural practices resulting in distinctive environmental exposures compared with Europeans or Americans, who are studied more. Although diverse and rapidly changing environments, as well as the high genetic variability of Africans and difference in linkage disequilibrium (ie, certain gene variants are inherited together more often than expected by chance), provide unparalleled potential to investigate the omics fields, only a small percentage of studies come from Africa. Furthermore, research evidence lags behind the practices of companies offering genetic testing for personalized medicine and nutrition. We need to generate more evidence on GxEs that also considers continental African populations to be able to prevent unethical practices and enable tailored treatments. This review aims to introduce nutrition professionals to genetics terms and valid methods to investigate GxEs and their challenges, and proposes ways to improve quality and reproducibility. The review also provides insight into the potential contributions of nutrigenetics and nutrigenomics to the healthcare sphere, addresses direct-to-consumer genetic testing, and concludes by offering insights into the field's future, including advanced technologies like artificial intelligence and machine learning.

Ethical, legal, and social issues related to genetics and genomics in cancer: A scoping review and narrative synthesis

Genomics is increasingly being incorporated into models of care for cancer. Understanding the ethical, legal, and social issues (ELSI) in this domain is important for successful and equitable implementation. We aimed to identify ELSI scholarship specific to cancer control and genomics. To do this, we undertook a scoping literature review and narrative synthesis, identifying 46 articles that met inclusion criteria. Eighteen ELSI themes were developed, including (1) equity of access, which included structural barriers to testing and research, access to preventive and follow-up care, and engagement with health systems; (2) family considerations, such as an ethical obligation to disseminate relevant genomic information to at-risk family members; (3) legal considerations, including privacy and confidentiality, genetic discrimination, and the prospective duty to reclassify variants; and (4) optimizing consent processes in clinical care and research. Gaps in the literature were identified with respect to equity for people living in rural or remote areas, and how to provide ethical care within culturally, linguistically, and ethnically diverse communities, including First Nations peoples. Our findings suggest a need for a multidisciplinary approach to examining ELSI in cancer genomics beyond initial test indication and within the broader context of the mainstreaming of genomics in health care.

Moving toward Equity through Embedded ELSI Ethnography

This paper describes the unique values of, challenges within, and opportunities presented by embedded ELSI ethnography. Drawing from our six-year embedded ELSI study of the WISDOM (Women Informed to Screen Depending on Measures of Risk) trial, we present three examples of the variable ways we engaged with the WISDOM trial's scientific team. WISDOM is a preference-sensitive, pragmatic, randomized controlled trial of risk-based breast cancer screening informed by genomics. Our embedded ELSI approach included multiple modes of engagement: (a) Trial investigators sought bioethics expertise; for example, we were asked to consult on traditional bioethics topics such as consent as well as more complex questions about whether to implement a specific risk-assessment approach on only one race-defined group of trial participants. (b) As the ELSI investigators, we identified ethical concerns in issues that surfaced via ethnography and considered them in the Bioethics Working Group; for example, there were concerns about the implementation processes that the WISDOM team viewed as logistical challenges. (c) Our presence in WISDOM working group conversations and our expertise on classic social science topics, including race and gender, offered opportunities to engage on the spot with topics such as how to include transgender participants in a trial initially focused on "women's health"; through such engagement, the value of social science became clear to the trial investigators. The paper elaborates on the dynamic relationship between our ethnographic observations, the Bioethics Working Group discussions, and the contributions of each to our real-time ELSI interventions in these examples. The methods and experiences we describe here suggest modes of engagement that, in combination, have the potential to expand the role of ELSI to offer real-time intervention on issues related to equity, inclusion, and justice in genetic and genomic research.

Exploring Genetic Testing for Rare Disorders of Obesity: Experience and Perspectives of Pediatric Weight Management Providers

Background: This study describes experiences and perspectives of pediatric weight management (PWM) providers on the implementation of genetic testing for rare causes of obesity. Methods: Purposive and snowball sampling recruited PWM providers via email to complete a 23-question survey with multiple choice and open-ended questions. Analyses include descriptive statistics, Fisher's exact test, one-way ANOVA with Tukey's post hoc test, and qualitative analysis. Results: Of the 55 respondents, 80% reported ordering genetic testing. Respondents were primarily physicians (82.8%) in practice for 11-20 years (42%), identified as female (80%), White (76.4%), and non-Hispanic (92.7%) and provided PWM care 1-4 half day sessions per week. Frequently reported patient characteristics that prompted testing did not vary by provider years of experience (YOE). These included obesity onset before age 6, hyperphagia, dysmorphic facies, and developmental delays. The number of patient characteristics that prompted testing varied by YOE (p = 0.03); respondents with 6-10 YOE indicated more patient characteristics than respondents with >20 YOE (mean 10.3 vs. mean 6.2). The reported primary benefit of testing was health information for patients/families; the primary drawback was the high number of indeterminate tests. Ethical concerns expressed were fear of increasing weight stigma, discrimination, and impact on insurance coverage. Respondents (42%) desired training and guidance on interpreting results and counseling patients and families. Conclusions: Most PWM providers reported genetic testing as an option for patient management. Provider training in genetics/genomics and research into provider and family attitudes on the genetics of obesity and the value of genetic testing are next steps to consider.

Ethical Aspects of Human Genome Research in Sports-A Narrative Review

Human genome research in sports raises complex ethical considerations regarding the intersection of genetics and athletic performance. Pursuing genetic enhancements must uphold fairness, equality, and respect for human dignity. This narrative review explores the ethical dimensions of human genome research in sports, its potential implications on athletes, and the integrity of sports. As a narrative review, this study synthesizes the existing literature and expert insights to examine the ethical aspects of human genome research in sports. This study extensively examined the current literature on genetics, sports performance, ethical concerns, human rights, and legal regulations within the European context. The literature was searched using the SPORTDiscus, Scopus, Google Scholar, and PubMed databases. Exploring human genome research in sports reveals significant ethical implications, including potential genetic discrimination, impacts on human rights, and creating a genetic underclass of athletes. There are also definite benefits surrounding genetic testing. In conclusion, this review contends that integrating ethical considerations into developing and applying genetic technologies in sports is crucial to upholding fundamental principles of fairness, equality, and respect for human dignity. It stresses the importance of open and inclusive dialogue about the potential consequences of genetic advancements on athletic performance, future generations, and the integrity of sports.

What's in a name? Justifying terminology for genomic findings beyond the initial test indication: A scoping review

Genome sequencing can generate findings beyond the initial test indication that may be relevant to a patient or research participant's health. In the decade since the American College of Medical Genetics and Genomics published its recommendations for reporting these findings, consensus regarding terminology has remained elusive and a variety of terms are in use globally. We conducted a scoping review to explore terminology choice and the justifications underlying those choices. Documents were included if they contained a justification for their choice of term(s) related to findings beyond the initial genomic test indication. From 3571 unique documents, 52 were included, just over half of which pertained to the clinical context (n = 29, 56%). We identified four inter-related concepts used to defend or oppose terms: expectedness of the finding, effective communication, relatedness to the original test indication, and how genomic information was generated. A variety of justifications were used to oppose the term "incidental," whereas "secondary" had broader support as a term to describe findings deliberately sought. Terminology choice would benefit from further work to include the views of patients. We contend that clear definitions will improve ethical debate and support communication about genomic findings beyond the initial test indication.

Genetics and Genomics Teaching in Nursing Programs in a Latin American Country

Although the importance of genetics and genomics in nursing education has been widely recognized, surveys carried out in several countries show that these subjects are still limited in nursing undergraduate programs. In Latin America, the teaching of genetics and genomics in nursing programs has never been previously documented. Considering this scenario, we aimed to investigate how genetics and genomics have been taught in undergraduate nursing programs in Brazil. A total of 138 undergraduate nursing program coordinators and 49 faculty members were recruited to participate in this cross-sectional study. After IRB approval, data were collected using an online survey, covering curriculum design, faculty credentials, genetics and/or genomics teaching, as well as their impressions regarding the document "Essential Nursing Competencies and Curricula Guidelines for Genetics and Genomics". Genetics is taught in most of the investigated courses (67.3%), mainly by biologists (77.6%), with master's degree (83.7%), and with the syllabus mainly focused on molecular biology. More instructors agreed with Competency 2 (C2) which refers to advocating for clients' access to desired genetic/genomic services and/or resources including support groups as well as C23 which refer to using health promotion/disease prevention practices that incorporate knowledge of genetic and genomic risk factors, than coordinators. That is, the participants' type of appointment (instructors vs. coordinators) had a significant effect on their agreement level with competencies C2 (χ2 = 6.23, p = 0.041) and C23 (χ2 = 9.36, p = 0.007). Overall, a higher number of participants with both master's and Ph.D. degrees significantly agreed with competencies C2, C4, which refer to incorporating genetic and genomic technologies and information into registered nurse practice, and C5-demonstrating in practice the importance of tailoring genetic and genomic information and services to clients based on their culture, religion, knowledge level, literacy, and preferred language, when compared to those with Ph.D. only, and those with a master's degree only (χ2 = 8.73, p = 0.033; χ2 = 8.61, p = 0.033; χ2 = 8.61, p = 0.033, respectively). Our results support reflections on ways to prepare the nursing workforce to deliver personalized nursing care. Additionally, they can be an aid in establishing guidelines for the undergraduate nursing curricula in Brazil and in other Portuguese-speaking countries, as well as in Latin America.
