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.

5 Αυγ 2020 · BRCA1 and BRCA2 are cancer-susceptibility genes, meaning that people who inherit pathogenic* mutations in either one have an increased risk of developing certain cancers. Hereditary (or “germline”) mutations in BRCA1 or BRCA2 cause Hereditary Breast and Ovarian Cancer Syndrome.
18 Ιουν 2020 · The breast cancer susceptibility genes known as BRCA1 and BRCA2 are specific genes found in human DNA. Everyone — men and women — inherit BRCA (an abbreviation for breast cancer, often pronounced bracka) genes from their parents. BRCA1 and BRCA2 are tumor suppressor genes, which, when they function normally, keep tumors from forming.
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.
Everyone has two types of breast cancer (“BRCA”) genes in every cell of their body. When functioning properly, BRCA1 and BRCA2 repair DNA, keep other genes healthy, and prevent cancerous changes in the cells. When a mutation damages either of these genes, the person’s risk of cancer increases.
Germline pathogenic variants in BRCA1/BRCA2 are associated with ovarian cancer, fallopian tube cancer, primary peritoneal cancer, male breast cancer, prostate cancer, pancreatic cancer, and early-onset breast cancer. BRCA1/BRCA2 -associated cancer risks are inherited in an autosomal dominant manner.
