Abstract excerpt
The MMR (DNA mismatch repair) system helps to maintain the integrity of the genome. This involves eliminating base-base mismatches and insertion/deletion loops, which can lead to microsatellite instability, as seen in tumour cells. Hereditary non-polyposis colon cancer is the result of dominant mutations in MMR genes, such as MLH1, MSH2 and MSH6. More recently there have been case reports of biallelic mutations...
