BRCA1 and ovarian carcinoma: Of the 62 total participants, eighteen subjects were identified as having 19 deleterious germline mutations in 6 different genes: BRCA1, BRCA2, CHEK2, PALB2, RAD51C, and STK11. The 19 deleterious germline mutations in these 6 tumor suppressor genes included 12 (63.2%) in BRCA1, 2 (10.5%) in BRCA2, and 5 (26.3%) in other genes that when mutated are potentially associated with an increased risk of ovarian cancer: 2 (10.5%) in PALB2, 1 (5.3%) in CHEK2, 1 (5.3%) in RAD51C, and 1 (5.3%) in STK11 (Fig. 1 and Fig. 4 and Table 1).
