Exome Sequencing–Based Screening for BRCA1/2 Expected Pathogenic Variants Among Adult Biobank Participants

Abstract
Pathogenic variants in the BRCA1 (OMIM 113705) and BRCA2 (OMIM 600185) genes were first associated with familial breast cancer risk in the mid-1990s.1,2 Associated risks for ovarian cancer, prostate cancer, pancreatic cancer, and melanoma have since been documented; these clinical associations are grouped as hereditary breast and ovarian cancer (HBOC) syndrome.3
