Two of the nonsense mutations (p.C675X and p.E1013X) in BRCA1, 7 of the frameshift (p.N1626*11, p.N3024*16, p.Q1429*8, p.L2092*6, p.K1057*7 (x2), and p.F1546*21) in BRCA2 and a single frameshift (p.Q60*6) in PALB2 would predispose the carrier to breast/ovarian cancer. This evidence concerns the gene BRCA2 and ovarian carcinoma.
