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 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.
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.
4 Σεπ 1998 · BRCA1- and BRCA2- associated HBOC is inherited in an autosomal dominant manner. The vast majority of individuals with a BRCA1 or BRCA2 pathogenic variant inherited it from a parent.
7 Φεβ 2020 · High-penetrance syndromes conferring an increased risk of breast, ovarian, and other gynecologic malignancies include BRCA1 and BRCA2 gene mutation–related syndromes, Lynch syndrome, Peutz-Jeghers syndrome (PJS), Li-Fraumeni syndrome (LFS), Cowden syndrome, and Gorlin syndrome.
faulty genes are the underlying cause for about 5–10% (5 to 10 in 100) of breast cancers. There are two genes that, if mutated, greatly increase an individual’s chance of developing breast and ovarian cancer. These are known as the BRCA1 (Breast Cancer 1) and BRCA2 (Breast Cancer 2) genes. These two genes account for approximately
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.
