Analysis of 5848 putative deletions delineated by gene regions identified a total of 52 loci associated (at unadjusted P<0.05) with breast cancer risk (Supplementary Table S6), and 72 CNV loci associated with ovarian cancer risk for BRCA1 pathogenic variant carriers (Supplementary Table S6). The gene discussed is BRCA1; the disease is ovarian cancer.
