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.

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.
P53 is a known gene involved in Li-Fraumeni cancer syndrome and could be identified in 20% ... Spanish studies could discover two major founder mutations with low frequency in both BRCA1/2 genes, the 330A>G substitution change in splice site between exon 5 and exon 6 which makes an inefficient truncated form of BRCA1 protein . The ...
BRCA1 and BRCA2 are both tumor suppressors whose mutations are the cause of most hereditary breast cancers. Both genes are highly involved in ensuring genome stability. BRCA1 homologs are found in the plant and animal kingdoms while BRCA2 homologs are additionally found in the fungi kingdom.
1 Σεπ 2004 · The discovery of the first gene associated with hereditary breast cancer, BRCA1, was anticipated to greatly increase our understanding of both hereditary and sporadic forms of breast...
1 Ιαν 2006 · Genetic testing. Ovarian cancer. 1. Background. In the European Union population, the number of breast and ovarian cancer cases diagnosed every year is 115/100,000 and 18/100,000, respectively.
10 Ιουν 2019 · Germline mutations in the BRCA1 and BRCA2 genes predispose carriers to breast and ovarian cancer, and there remains a need to identify the specific genomic mechanisms by which cancer evolves in these patients. Here we present a systematic genomic analysis of breast tumors with BRCA1 and BRCA2 mutations. Methods.
