A family history of ovarian cancer was reported by 34.2% (609/1779) of women with a PV in BRIP1, 33.1% (283/855) of women with a PV in RAD51C, and 34.5% (157/455) of women with a PV in RAD51D. This was similar to what was reported for BRCA1, where 35.1% (2496/7114) of carriers had a family history of ovarian cancer. This evidence concerns the gene RAD51C and ovarian cancer.
