## Dear Sir, Fewer than 1% of all breast cancers occur in males. 1 Known risk factors for male breast cancer primarily include Klinefelter syndrome and other clinical conditions associated with aberrant hormonal status (e.g., benign breast disease and gynecomastia, liver cirrhosis, estrogen therap

## Abstract The __CHEK2__ 1100delC mutation was recently identified as a low‐penetrance breast cancer susceptibility allele. The mutation occurred more frequently in families with clustering of breast and colorectal cancers (CRCs) than in families with clustering of breast cancer only. Hence, the 1
## Abstract Searching for low‐penetrance genes involved in breast cancer susceptibility has been a field of interest in the last few years. Recently, the CHEK 2 gene, involved in DNA damage and replication checkpoints, has been pointed out as a good candidate; moreover, a specific variant in this g
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
