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.

23 Δεκ 2011 · BRCA1 is a pleiotropic DDR protein that functions in both checkpoint activation and DNA repair, whereas BRCA2 is a mediator of the core mechanism of homologous recombination.
BRCA1 and BRCA2 are large genes in which multiple different types of pathogenic variant have been identified. The majority of these variants are individually rare, and several have only been reported in single families (so-called ‘private’ variants).
23 Μαΐ 2024 · Two well-described tumour-suppressor genes involved in genome maintenance are BRCA1 and BRCA2. Mutations in the BRCA1 and BRCA2 genes are prevalent in hereditary forms of breast, ovarian, prostate, and pancreatic cancer [2–5], but also occur in about 5% of sporadic tumours [6–9].
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...
18 Ιουλ 2020 · BRCA1 and BRCA2 are the genes related with breast and ovarian cancer. They have function in DNA repair processes and thus they are tumor suppressor genes. There are hundreds of mutations identified in these genes.
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.
