Genes related to breast cancer
Linkage analysis of DRD2, a marker linked to the ataxia-telangiectasia gene, in 64 families with premenopausal bilateral breast cancer. Cancer Res. Nov 1 . Most inherited cases of breast cancer are associated with mutations in two genes : BRCA1 and BRCA2. Learn more about genetic mutations linked to breast. About 5% to 10% of breast cancers are thought to be hereditary, So a gene linked to breast cancer could be activated by another gene it. Other Breast Cancer Genes Genes. Family history is one of the unavoidable genetic risk factors for developing breast sexinbelgium.infog research is helping identify the genes that are responsible for this inherited increased risk. BRCA1 and BRCA2 gene mutations are currently the best-known and most discussed genetic risk factors, but new genetic links are being discovered regularly. The name “BRCA” is an abbreviation for “BReast CAncer gene.” BRCA1 and BRCA2 are two different genes that have been found to impact a person’s chances of developing breast cancer. Every human has both the BRCA1 and BRCA2 genes. Despite what their names might suggest, BRCA genes do not cause breast cancer. These genes are described as "high penetrance" because they are associated with a high risk of developing breast cancer, ovarian cancer, and several other types of cancer in women who have mutations. Men with mutations in these genes also have an increased risk of developing several forms of cancer, including breast cancer.
