The CHEK2 kinase is a tumor suppressor whose activation in response to DNA double-strand breaks contributes to cell cycle arrest or apoptosis. The c.1100delC mutation is associated with familial breast cancer, and tumors from mutation carriers show reduced or absent CHEK2 protein expression. We have

Reports on the prognosis of familial breast cancer patients have been contradictory. True differences in survival, if they exist, would have important implications for genetic counselling and in treatment of hereditary breast cancer. We assessed the survival rates of 359 familial breast cancer patie
## Abstract Our current understanding of breast cancer susceptibility involves mutations in the 2 major genes __BRCA1__ and __BRCA2__, found in about 25% of highβrisk families, as well as few other low penetrance genes such as __ATM__ and __CHEK2__. Approximately twoβthirds of the multiple cases fa
