title: Mismatch repair defects in cancer.
abstract: Post-replicative mismatch repair in humans utilises the hMSH2, hMSH6, hMSH3, hMLH1 and hPMS2 genes and possibly the newly identified hMLH3 gene. Recently, a link has been established between hMSH6 mutations and 'atypical' hereditary non-polyposis colon cancer (HNPCC) with an increased incidence of endometrial cancers. To satisfy the need for a diagnostic test capable of differentiating between pathogenic mutations and polymorphisms, several functional assays that fulfil these criteria have been described. These should allow for better diagnosis of HNPCC.
