Where is the BRCA1 protein located?

The human BRCA1 gene is located on the long (q) arm of chromosome 17 at region 2 band 1, from base pair 41,196,312 to base pair 41,277,500 (Build GRCh37/hg19) (map). BRCA1 orthologs have been identified in most vertebrates for which complete genome data are available.

Where are BRCA1 and 2 located?

Two genes, BRCA1, located on chromosome 17q21 (5,6), and BRCA2, located on 13q12-13 (7–9), have been shown to predispose to familial breast cancer.
