Genomic sequencing in diverse and underserved pediatric populations

Abstract

Purpose: Limited evidence evaluates parents' perceptions of their child's clinical genome-scale sequencing (GS) results, particularly among individuals from medically underserved groups. Five Clinical Sequencing Evidence-Generating Research consortium studies performed GS in children with suspected genetic conditions with high proportions of individuals from underserved groups to address this evidence gap. Methods: Parents completed surveys of perceived understanding, personal utility, and test- related distress after GS result disclosure. We assessed outcomes' associations with child- and parent-related factors: child age; type of GS finding; and parent health literacy, numeracy, and education. Results: A total of 1763 parents completed surveys; 83% met "underserved" criteria based on race, ethnicity, and risk factors for barriers to access. We observed high perceived understanding and personal utility and low test-related distress. Outcomes were associated with the type of GS finding; parents of children with a pathogenic or likely pathogenic finding endorsed higher personal utility and more test-related distress than those whose children had a variant of uncertain significance or normal finding. Personal utility was higher in parents who met the criteria for "underserved." Conclusion: Our findings shed light on correlates of parents' cognitive and emotional responses to their child's GS findings and emphasize the need for tailored support in disclosure discussions.
