Blood samples taken in two GOG studies (GOG 218 and GOG 262) were subjected to genetic testing and showed a BRCA1/2 mutation in 13.7 % of the patients with ovarian carcinoma, as well as mutations in other genes, in particular BRIP1, PALB2, CHEK2, NBN, and ATM, in 5.6 % of the patients [8]. Here, BRCA1 is linked to ovarian carcinoma.
