While the highest prevalence of BRCA1/2 mutation carriers was in patients diagnosed with double primary OC and BC, mutations in RAD51C/RAD51D/BRIP1 prevailed in patients diagnosed with OC only (Figure 2B); nevertheless, their distribution among histological subtypes was similar to that in BRCA1/2 mutation carriers (Figure 2E). The gene discussed is RAD51D; the disease is breast cancer.
