Genetic research aimed at understanding human health and disease is grounded in the study of genetic variation. The inclusion of research subjects with diverse ancestral backgrounds is essential for genetic and genomic research that fully explores human diversity. Large-scale cohort studies and biobanks in Europe and the United States often do not include the breadth of ethnic and racial diversity observed in their countries' citizens. This article explores the findings of a qualitative study of U.S. scientists' understanding and views of (...) the NIH Policy and Guidelines on the Inclusion of Minorities as Subjects in Clinical Research. The findings suggest that the policy restricts how scientists use racial and ethnic categories to define and report their study populations and does little to motivate their efforts to increase the inclusion of non-European ancestral populations in genetic and genomic research.

Expectations of receiving personal health information as a fringe benefit of biospecimen donation—termed diagnostic misconception—are increasingly documented. We developed an instrument measuring conflation of observational biospecimen-based research and clinical care for use with Latino communities, who may be particularly affected by diagnostic misconception due to limited health care access.

As genetic and genomic research has progressed since the sequencing of the human genome, scientists have continued to struggle to understand the role of genetic and socio-cultural factors in racial and ethnic health disparities. Recognition that race and ethnicity correlate imperfectly with differences in allele frequency, environmental exposures, and significant health outcomes has made framing the relationship between genetic variation, race, ethnicity, and disease one of the most heated debates of the genome era. Because racial and ethnic identities reflect a (...) complicated mix of social and genetic factors, critics have argued that use of racial and ethnic categories as analytical variables in biomedical research lacks rigor, leads to potentially dangerous stereotyping in medical practice, and sends harmful messages of innate racial difference to the broader public.Concerns over the current lack of diversity in human genetic and genomic studies have developed in parallel to discussions of the appropriate use of racial and ethnic categories during the research process.
