Abstract
The frame-shift mutation 1100delC in the cell-cycle-checkpoint kinase 2 gene (CHEK2) has been reported to be a low penetrance breast cancer gene in Northern European populations. However, the variant may be relevant for breast cancer risk in other populations, due to its low prevalence. Recent studies have proposed a role for the mutation in colorectal cancer, finding a strong association between the CHEK21100delC mutation and hereditary breast and colorectal cancer (HBCC). A previous study suggested that the CHEK21100delC variant was not of clinical relevance in Spanish breast/ovarian cancer families. Here, we demonstrate that this genetic variant is not of clinical relevance for HNPCC and HBCC Spanish families.
