Recruiting research participants based on genetic information generated about them in a prior study is a potentially powerful way to study the functional significance of human genetic variation, but it also presents ethical challenges. To inform policy development on this issue, we conducted a survey of U.S. institutional review board chairs concerning the acceptability of recontacting genetic research participants about additional research and their views on the disclosure of individual genetic results as part of recruitment. Our findings suggest there is (...) unlikely to be a “one-size-fits-all” solution, but rather several ethically acceptable approaches to genotype-driven recruitment, depending on context. Disclosures made during the consent process for the original study and the clinical validity of the results are key considerations. Researchers must be prepared to communicate and answer questions in clear lay language about what is known and not known regarding the role of genetics in their proposed area of research. (shrink)
