“…A majority of research participants 1 , 2 , 3 and researchers 4 , 5 favor returning such results to participants, and many research studies that collect genomic data have written policies encouraging the return of actionable genomic results to participants (gRoR). 6 , 7 , 8 , 9 Yet the vast majority of such studies in the US and around the world have not implemented gRoR because of uncertainties around how to consent participants; which genes to select for return; how to analyze, classify, and report research variants; the logistics of recontacting participants; regulatory requirements necessitating the confirmation of research results; the transition of research participants into an appropriate clinical workstream; and the effort and cost associated with each of these steps. 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 Despite these challenges, it is likely that research participants will increasingly expect gRoR in genomic research.…”
