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.
Inheriting one BRCA1 mutation and one BRCA2 mutation has been reported occasionally; the child's risk for any given type of cancer is the higher risk of the two genes (e.g., the ovarian cancer risk from BRCA1 and the pancreatic cancer risk from BRCA2). Inheriting two BRCA2 mutations produces Fanconi anemia. [9]: 82–85
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.
GT198 is located at the long arm of human chromosome 17 (17q21). GT198 spans 5.5 kilobase pairs (Kb) and contains eight exons. GT198 is located 470 Kb proximal to BRCA1 and 2.9 megabase pairs (Mb) distal to Her2/neu between the two cancer genes. It is currently unknown if genetic instability of each gene could affect neighboring cancer genes.
