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.

Abstract. The proteins encoded by the two major breast cancer susceptibility genes, BRCA1 and BRCA2, work in a common pathway of genome protection. However, the two proteins work at different stages in the DNA damage response (DDR) and in DNA repair.
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).
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.
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...
27 Οκτ 2024 · BRCA1 and BRCA2 are the first two genes found to be associated with inherited forms of breast cancer and ovarian cancer. People with mutations in either BRCA1 or BRCA2 have a much higher risk for developing breast, ovarian or other types of cancer than those without mutations in the genes.
A large, single-institution study of more than 1,000 carriers of pathogenic variants found a 21-fold increased risk of pancreatic cancer among BRCA2 carriers and a 4.7-fold increased risk among carriers of BRCA1 pathogenic variants, compared with incidence in the general population.
