BRCA2 and cancer: Myriad Genetics is a biotechnology company based in Salt Lake City which holds patents on a number of cancer-linked human genes, including BRCA1 and BRCA2. Myriad offers genetic diagnostic tests for mutations in these genes, which allow physicians and genetic counsellors to better assess their patients’ risk of developing a hereditary cancer and tailor risk management strategies such as prophylactic therapy to that risk profile.
