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 gene pathogenic variants account for most hereditary breast cancer and are increasingly used to determine eligibility for PARP inhibitor (PARPi) therapy of BRCA-related cancer.
The greatest risk factor for breast and ovarian cancer is inheritance of a mutation in one of the breast cancer susceptibility genes, BRCA1 or BRCA2. BRCA1 and BRCA2 are tumour suppressor genes, the coding regions of which show no homology to previously described proteins or to each other.
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.
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.
10 Ιουν 2019 · We identified 11 genes that are enriched for indels and structural variant breakpoints in BRCA1/2-mutated tumors. 4 of these genes (PTEN, RB1, TP53 and RUNX1) are known tumor suppressors and have also been identified as potential point mutation driver genes , showing that in BRCA1/2-mutated tumors, structural variants often inactivate the same ...
10 Ιαν 2018 · Breast cancer genes 1 and 2, BRCA1/2 have been very well studied since their discovery in 1994 and 1995. Disease-causing mutations in these genes give a high lifetime risk of both breast and ovarian cancer [1, 2, 3].
