"Mutation analysis of the CHK2 gene in families with hereditary breast cancer."

Allinen M, Huusko P, Mantyniemi S, Launonen V, Winqvist R



Published July 20, 2001 in Br J Cancer volume 85 .

Pubmed ID: 11461078

Abstract:
Recently CHK2 was functionally linked to the p53 pathway, and mutations in these two genes seem to result in a similar Li-Fraumeni syndrome (LFS) or Li-Fraumeni-like syndrome (LFL) multi-cancer phenotype frequently including breast cancer. As CHK2 has been found to bind and regulate BRCA1, the product of one of the 2 known major susceptibility genes to hereditary breast cancer, it also more directly makes CHK2 a suitable candidate gene for hereditary predisposition to breast cancer. Here we have screened 79 Finnish hereditary breast cancer families for germline CHK2 alterations. Twenty-one of these families also fulfilled the criteria for LFL or LFS. All families had previously been found negative for germline BRCA1, BRCA2 and TP53 mutations, together explaining about 23% of hereditary predisposition to breast cancer in our country. Only one missense-type mutation, Ile(157)-->Thr(157), was detected. The high Ile(157)--> Thr(157)mutation frequency (6.5%) observed in healthy controls and the lack of other mutations suggest that CHK2 does not contribute significantly to the hereditary breast cancer or LFL-associated breast cancer risk, at least not in the Finnish population. For Ile(157)--> Thr(157)our result deviates from what has been reported previously.
