The MSH2 gene provides instructions for making a protein that plays an essential role in repairing DNA. This protein helps fix errors that are made when DNA is copied (DNA replication) in preparation for cell division. MSH2 is a tumor suppressor gene and more specifically a caretaker gene that codes for a DNA mismatch repair (MMR) protein, MSH2, which forms a heterodimer with MSH6 to make the human MutSα mismatch repair complex. It also dimerizes with MSH3 to form the MutSβ DNA repair complex.

Mutations in DNA MMR genes, mainly MSH2 and MLH1, account for the majority of HNPCC, an autosomal dominant predisposition to colorectal cancer and other malignancies. The evaluation of many questions regarding HNPCC requires clinically and genetically well-characterized HNPCC patient cohorts of reasonable size.

In total, 107 of the 423 women (25.3%) had been Sep 27, 2006 genes MLH1 and MSH2. Objectives To analyze MLH1/MSH2 mutation prevalence in a large cohort of pa- tients undergoing genetic testing and Jan 1, 2008 MSH2 variants classified by the InSiGHT consortium: criteria used for MSH2 ( mutS homolog 2, colon cancer, nonpolyposis type 1 (E.

Among MSH2 mutation carriers, MLH1 was expressed in both tumor types, whereas MSH2 and, in many cases, also MSH6, were absent. Remarkably, among MLH1 mutation carriers, 54% of ECs (21 of 39), but none of the CRCs (0 of 32), lacked the MSH2 and/or MSH6 protein in addition to lacking MLH1 protein expression. However, the higher risk of stomach cancer (up to 6%) in MLH1 mutation carriers should be a cause for concern, especially since one recent study reported similar elevated cumulative risks of 4% and 7% by age 70 years for MLH1 and MSH2 mutation carriers, respectively. 34 The issue of gastric surveillance should be addressed.
