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 variants may cause a: higher-than-average risk of ovarian cancer; slightly higher-than-average risk of pancreatic cancer. And BRCA2 gene variants may also cause a higher-than-average risk of: prostate cancer; breast cancer in men and people assigned male at birth.
Women with a BRCA1 or BRCA2 (BRCA1/2) inherited gene mutation may be called BRCA1/2 carriers. Most risk factors for breast cancer in women likely impact risk the same way for women who are BRCA1/2 carriers and women who are non-carriers.
Inheriting damaged copies of the BRCA1 or BRCA2 genes can increase the risk for breast cancer and ovarian cancer in women and the risk for breast and prostate cancer in men, as well as other cancers. Here is what you need to know about genetic factors in breast cancer, who may be at risk and how people with BRCA mutations can work with their ...
23 Ιουλ 2023 · Breast cancer genes BRCA1 and BRCA2 are tumor suppressor genes whose mutations significantly increase the likelihood of developing particular types of epithelial malignancies, namely breast and ovarian cancer.
BRCA1 and BRCA2 are genes involved in DNA repair. Constitutional (germline) pathogenic variants in these genes are associated with hereditary breast and ovarian cancer, as well as other cancers.
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
