The chromosomal location of BRCA1 was discovered by Mary-Claire King's team at UC Berkeley in 1990. [21] After an international race to refine the precise location of BRCA1, [22] the gene was cloned in 1994 by scientists at University of Utah, National Institute of Environmental Health Sciences (NIEHS) and Myriad Genetics.
BRCA-related breast cancer appears at an earlier age than sporadic breast cancer. [9]: 89–111 It has been asserted that BRCA-related breast cancer is more aggressive than normal breast cancer, however most studies in specific populations suggest little or no difference in survival rates despite seemingly worse prognostic factors.
Absolute risk of cancers in BRCA1 or BRCA2 mutation. [4]A number of genes are associated with HBOC. [5] The most common of the known causes of HBOC are: BRCA mutations: [5] Harmful mutations in the BRCA1 and BRCA2 genes can produce very high rates of breast and ovarian cancer, as well as increased rates of other cancers.

Mary-Claire King was born on February 27, 1946, to Harvey and Clarice King of Wilmette, Illinois, near Chicago.Her father worked for Standard Oil of Indiana. [1] When King was 15 years old, her childhood best friend died of cancer.
The BRCA1 and BRCA2 genes are centrally involved in HR, DNAdamage repair, end resection, and checkpoint signaling. Mutational signatures of HRD have been identified in over 20% of breast cancers, as well as pancreatic, ovarian, and gastric cancers. BRCA1/2 mutations confer sensitivity to platinum-based chemotherapies.
