A survey of aortic disease biorepository participants’ preferences for return of research genetic results

There is ongoing debate on whether and what research genetic results to return to study participants. To date, no study in this area has focused on aortopathy populations despite known genes that are clinically actionable. Participants (n = 225, 79% male, mean age = 61 years) with an aortopathy were surveyed to assess preferences for receiving research genetic results. Participants were 'very' or 'extremely likely' to want results for pathogenic variants in aortopathy genes with implications for family members (81%) or that would change medical management (76%). Similarly, participants were 'very' or 'extremely likely' to want actionable secondary findings related to cancer (75%) or other cardiac diseases (70%). Significantly lower interest was observed for non-actionable findings-pathogenic variants in aortopathy genes that would not change medical management (51%) and variants of uncertain significance (38%) (p .0001). Higher health and genomic literacy were positively associated with interest in actionable findings. Most participants (63%) were accepting of any means of return; however, a substantial minority (18%-38%) deemed certain technological means unacceptable (e.g., patient portal). Over 90% of participants reported that a range of health professionals, including cardiovascular specialists, genetics specialists, and primary care providers, were acceptable to return results. Participants with aortopathies are highly interested in research genetic results perceived to be medically actionable for themselves or family members. Participants are accepting of a variety of means for returning results. Findings suggest that research participants should be asked what results are preferred at time of informed consent and that genetic counseling may clarify implications of results that are not personally medically actionable.
