Choices, attitudes, and experiences of genetic screening in Latino/a and Ashkenazi Jewish individuals

Abstract

Genetic screening to inform personal risk has only recently become an option as the cost of sequencing decreases, and our ability to interpret sequence variants improves. Studies have demonstrated that people want to learn about their genetic information and do well after learning it, but minorities are underrepresented in these studies. We surveyed Ashkenazi Jewish (AJ) and Latino/a participants in a genetic screening study to solicit choices about genetic results to return, as well as their experience with learning these results and attitudes about genetic information secrecy and security. Participants had the option to proceed through the study self-guided, and few elected to have traditional pre-test genetic education and counseling. Despite this, the majority were satisfied with the process of selecting and receiving genetic results and felt that they understood their results. Concerns about privacy and confidentiality of genetic data were minimal, though some participants expressed modest concerns about keeping any potential results secret or the confidentiality of their genetic information. Our results support the feasibility of the option of self-guided genetic screening. Additional care will need to be taken when designing population-based screening studies to meet the needs of participants who come from communities with different experiences with genetics.
