Perspectives and preferences regarding genomic secondary findings in underrepresented prenatal and pediatric populations: A mixed-methods approach

Abstract

PurposePatients undergoing clinical exome sequencing (ES) are routinely offered the option to receive secondary findings (SF). However, little is known about the views of individuals from underrepresented minority pediatric or prenatal populations regarding SF. MethodsWe explored the preferences for receiving hypothetical categories of SF (H-SF) and reasons for accepting or declining actual SF through surveying (n = 149) and/or interviewing (n = 47) 190 families undergoing pediatric or prenatal ES. ResultsUnderrepresented minorities made up 75% of the probands. In total, 150 families (79%) accepted SF as part of their child/fetus’s ES. Most families (63%) wanted all categories of H-SF. Those who declined SF as part of ES were less likely to want H-SF across all categories. Interview findings indicate that some families did not recall their SF decision. Preparing for the future was a major motivator for accepting SF, and concerns about privacy, discrimination, and psychological effect drove decliners. ConclusionA notable subset of families (37%) did not want at least 1 category of H-SF, suggesting more hesitancy about receiving all available results than previously reported. The lack of recollection of SF decisions suggests a need for alternative communication approaches. Results highlight the importance of the inclusion of diverse populations in genomic research.
