Tyrer–Cuzick Lifetime Risk Is Not Associated With Non‐BRCA1/2 Pathogenic Variants for Breast Carcinoma

TC scores provide valuable information regarding the lifetime risk of an individual of developing breast cancer. However, the study found they were not associated with prediction of non-BRCA1/2 PVs. When choosing a genetic testing panel for breast cancer genes, TC is not as a reliable predictor on individual patient's family history, NCCN guidelines, or ASBrS guidelines. Our study supports the need to develop a genetic risk calculator that incorporates the predictive value for these non-BRCA1/2 PVs in otherwise low or average TC women.
