The BRCA2 gene, also known as BRCC2, BROVCA2, FAD, FACD, FAD1, GLM3, FANCD, PNCA2, FANCD1 and XRCC11, functions as a tumour suppressor gene and is involved in repairing damaged DNA, and mutations of it are associated with diseases including fanconi anaemia, complementation group D1, fallopian tube cancer, primary peritoneal cancer, ovarian cancer and breast cancer.20 Numerous reports have indicated that inherited germline mutations in the BRCA19, 21, 22 and BRCA2 genes10, 23, 24, 25 result in an increased risk of developing breast or ovarian cancer sometime during their life‐times. The gene discussed is BRCA2; the disease is breast carcinoma.
