    A content analysis of the views of genetics professionals on race, ancestry, and genetics.

    Over the past decade, the proliferation of genetic studies on human health and disease has reinvigorated debates about the appropriate role of race and ancestry in research and clinical care. Here we report on the responses of genetics professionals to a survey about their views on race, genetics, and ancestry across the domains of science, medicine, and society. Through a qualitative content analysis of free-text comments from 515 survey respondents, we identified key themes pertaining to multiple meanings of race, the use of race as a proxy for genetic ancestry, and the relevance of race and ancestry to health. Our findings suggest that for many genetics professionals the questions of what race is and what race means remain both professionally and personally contentious. Looking ahead as genomics is translated into the practice of precision medicine and as learning health care systems offer continued improvements in care through integrated research, we argue for nuanced considerations of both race and genetic ancestry across research and care settings.

    Characterization of the standard and recommended CODIS markers.
    (Journal of forensic sciences, 2013-01) Katsanis, Sara H; Wagner, Jennifer K
    As U.S. courts grapple with constitutional challenges to DNA identification applications, judges are resting legal decisions on the fingerprint analogy, questioning whether the information from a DNA profile could, in light of scientific advances, reveal biomedically relevant information. While CODIS loci were selected largely because they lack phenotypic associations, how this criterion was assessed is unclear. To clarify their phenotypic relevance, we describe the standard and recommended CODIS markers within the context of what is known currently about the genome. We characterize the genomic regions and phenotypic associations of the 24 standard and suggested CODIS markers. None of the markers are within exons, although 12 are intragenic. No CODIS genotypes are associated with known phenotypes. This study provides clarification of the genomic significance of the key identification markers and supports--independent of the forensic scientific community--that the CODIS profiles provide identification but not sensitive or biomedically relevant information.

    Personal DNA testing in college classrooms: perspectives of students and professors.
    (Genetic testing and molecular biomarkers, 2013-06) Daley, Lori-Ann A; Wagner, Jennifer K; Himmel, Tiffany L; McPartland, Kaitlyn A; Katsanis, Sara H; Shriver, Mark D; Royal, Charmaine D
    Discourse on the integration of personal genetics and genomics into classrooms is increasing; however, limited data have been collected on the perspectives of students and professors. We conducted a cross-sectional survey of undergraduate and graduate students as well as professors at two major universities to assess attitudes regarding the use of personal DNA testing and other personalized activities in college classrooms. Students indicated that they were more likely to enroll (60.2%) in a genetics course if it offered personal DNA testing; undergraduate students were more likely than graduate students to enroll if personal DNA testing was offered (p=0.029). Students who majored in the physical sciences were less likely to enroll than students in the biological or social sciences (p=0.019). Students also indicated that when course material is personalized, the course is more interesting (94.6%) and the material is easier to learn (87.3%). Professors agreed that adding a personalized element increases student interest, participation, and learning (86.0%, 82.6%, and 72.6%, respectively). The results of this study indicate that, overall, students and professors had a favorable view of the integration of personalized information, including personal DNA testing, into classroom activities, and students welcomed more opportunities to participate in personalized activities.

    Preliminary perspectives on DNA collection in anti-human trafficking efforts.
    (Recent advances in DNA & gene sequences, 2014-01) Katsanis, Sara H; Kim, Joyce; Minear, Mollie A; Chandrasekharan, Subhashini; Wagner, Jennifer K
    Forensic DNA methodologies have potential applications in the investigation of human trafficking cases. DNA and relationship testing may be useful for confirmation of biological relationship claims in immigration, identification of trafficked individuals who are missing persons, and family reunification of displaced individuals after mass disasters and conflicts. As these applications rely on the collection of DNA from non-criminals and potentially vulnerable individuals, questions arise as to how to address the ethical challenges of collection, security, and privacy of collected samples and DNA profiles. We administered a survey targeted to victims' advocates to gain preliminary understanding of perspectives regarding human trafficking definitions, DNA and sex workers, and perceived trust of authorities potentially involved in DNA collection. We asked respondents to consider the use of DNA for investigating adoption fraud, sex trafficking, and post-conflict child soldier cases. We found some key differences in perspectives on defining what qualifies as "trafficking." When we varied terminology between "sex worker" and "sex trafficking victim" we detected differences in perception on which authorities can be trusted. Respondents were supportive of the hypothetical models proposed to collect DNA. Most were favorable of DNA specimens being controlled by an authority outside of law enforcement. Participants voiced concerns focused on privacy, misuse of DNA samples and data, unintentional harms, data security, and infrastructure. These preliminary data indicate that while there is perceived value in programs to use DNA for investigating cases of human trafficking, these programs may need to consider levels of trust in authorities as their logistics are developed and implemented.
