BRCA1
Quick Summary
BRCA1 is a tumor suppressor gene that plays a crucial role in repairing DNA damage and maintaining genetic integrity within cells. Mutations in BRCA1, and its related gene BRCA2, significantly increase the risk of developing certain cancers, most notably breast cancer and ovarian cancer. These genes are often referred to as BRCA genes, an abbreviation for breast cancer genes. The discovery of BRCA1 in 1994 by Mary-Claire King marked a significant advancement in understanding hereditary forms of breast cancer.12

breast cancerCauses and symptomsin genes called HER2, BRCA1, BRCA2, CHEK2, and p53 have been linked to breast cancer. These mutations may be inherited or acquired. Mutations that are inherited often substantially increase a person’s risk for developing breast cancer. For example, whereas some 12 percent of women in the general population develop…

human genetic diseaseGenetics of cancer…one of two specific genes, BRCA1 and BRCA2, account for at least half of the cases observed. The BRCA1 and BRCA2 genes both encode protein products believed to function in the pathways responsible for sensing and responding to DNA damage in cells. While a woman in the general population has…
