BRCA2 (P51587) variants and mutations

BRCA2 (also known as P51587) is a human protein-coding gene encoding a breast cancer type 2 susceptibility protein. It loads RAD51 onto damaged DNA to enable homologous recombination and also protects stressed replication forks from degradation. Germline loss-of-function variants strongly predispose to breast, ovarian, prostate, pancreatic, and other cancers. This analysis covers 16,922 BRCA2 variants and mutations. Of these, 59% have computational variant effect predictions. Disease context includes breast cancer, Fanconi anemia complementation group D1, and cancer. Example BRCA2 variants include M1?, M1I, and M1K.
