BRCA1 (BReast CAncer gene 1) and BRCA2 (BReast CAncer gene 2) are genes that produce proteins that help repair damaged DNA. Everyone has two copies of each of these genes—one copy inherited from each parent.

BRCA1 and BRCA2 are tumour suppressor genes, the coding regions of which show no homology to previously described proteins or to each other. If one copy of either gene is mutated in the germ line, the result is hereditary breast and ovarian cancer (HBOC) syndrome, which is inherited in an autosomal-dominant manner.
23 Ιουλ 2023 · Both BRCA1 and BRCA2 are thought to act as tumor suppressor genes. Over the decades, it has been shown that mutations in the BRCA genes can lead to the development of breast, ovarian, prostate and colon cancer. In excess of 100 discrete germline mutations in BRCA1 and BRCA2 have been identified.
3 Μαρ 2023 · Genetics. Germline pathogenic variants in BRCA1/BRCA2 are associated with ovarian cancer, fallopian tube cancer, primary peritoneal cancer, male breast cancer, prostate cancer, pancreatic cancer, and early-onset breast cancer. BRCA1/BRCA2 -associated cancer risks are inherited in an autosomal dominant manner.
12 Αυγ 2016 · BRCA1 and BRCA2 are tumour-suppressor genes encoding proteins that are essential for the repair of DNA double-strand breaks by homologous recombination (HR). Cells that lack either BRCA1 or...
