The company that made BRCA testing a business, now selling hereditary panels and the myChoice, EndoPredict and Prolaris tumour tests.
Myriad held the BRCA1/2 gene patents until the 2013 US Supreme Court ruling and launched BRACAnalysis CDx (2014) and myChoice CDx (2019), the two FDA-approved companion diagnostics for PARP inhibitors. MyRisk is its hereditary cancer panel; EndoPredict (breast) and Prolaris (prostate) are its prognostic tests. Its history is a case study in how gene patents, guidelines and reimbursement shape which tests patients receive.
The inherited BRCA test that decides who can have PARP inhibitor pills for ovarian, breast, pancreatic and prostate cancer.
A tumour test that measures DNA-repair scarring so that women with ovarian cancer beyond BRCA carriers can benefit from PARP inhibitors.
A 12-gene test that combines gene activity with tumour size and lymph nodes to say whether hormone therapy alone is enough, and whether to continue it beyond five years.
A gene test on a prostate biopsy that estimates how aggressive the cancer is, to help decide between active surveillance and treatment.
