MSH2 mutS homolog 2. Component of the post-replicative DNA mismatch repair system (MMR). Forms two different heterodimers: MutS alpha (MSH2-MSH6 heterodimer) and MutS beta (MSH2-MSH3 heterodimer) which binds to DNA mismatches thereby initiating DNA repair. When bound, heterodimers bend the DNA helix and shields approximately 20 base pairs.

In this first report from Pakistan, we investigated the prevalence of pathogenic MLH1/MSH2/MSH6 variants in colorectal cancer (CRC) patients. Methods Consecutive cases (n = 212) were recruited at the Shaukat Khanum Memorial Cancer Hospital and Research Centre (SKMCH&RC MSH2 variants classified by the InSiGHT consortium: criteria used for classification are available here.We encourage submission of relevant unpublished information to assist in the classification of variants via LOVD or this template which can be emailed to the curator.

2002-07-09 · MSH2 is a tumor suppressor linked to hereditary nonpolyposis colorectal cancer (HNPCC), alterations in the p53 gene are the most frequent mutations found in a variety of different tumors

MSH2Z : Lynch syndrome (also known as hereditary nonpolyposis colorectal cancer: HNPCC) is an autosomal dominant hereditary cancer syndrome associated with germline variants in the mismatch repair genes, MLH1, MSH2, MSH6, and PMS2. Deletions within the 3-prime end of the EPCAM gene have also been associated with Lynch syndrome, as this leads to inactivation of the MSH2 promoter. The Msh2 (mutS homolog 2) gene encodes a homolog of the E. coli mismatch repair gene mutS. Mutations in Msh2 are associated with hereditary nonpolyposis colon cancer (HNPCC). Mice homozygous for the knockout allele are viable and fertile. Beginning at two months of age, some MSH2-mice develop lymphoid tumors containing microsatellite instabilities. .
