In physiology, BRCA1 gene (BRCA-1 gene) is "a tumor suppressor gene located on human chromosome 17 at locus 17q21. Mutations of this gene are associated with the formation of familial breast and ovarian cancer. It encodes a large, nuclear protein that is a component of DNA repair pathways."[1]
Women who have BRCA1 or BRCA2 genes, especially if there is a familial history of breast cancer, may be candidates for prophylactic mastectomy. [2]
