BRCA genes are also involved in the development of sporadic breast and ovarian tumors; and patients, carrying a germline or somatic BRCA1/BRCA2 variants, may benefit from PARP inhibitors therapy (Coleman et al., 2017; Robson et al., 2017; Oza et al., 2018; Litton et al., 2018). This evidence concerns the gene BRCA2 and ovarian neoplasm.
