Although most mutations of MSI are the result of frame-shift mutations, occasionally the mutation events leading to MSI are derived from the hypermethylation of the hMLH1 (MMR protein) promoter. Hypermethylation occurs when a methyl group is added to a DNA nucleotide, resulting in gene silencing, thus yielding MSI.
DNA mismatch repair (MMR) is a system for recognizing and repairing erroneous insertion, deletion, and mis-incorporation of bases that can arise during DNA replication and recombination, as well as repairing some forms of DNA damage.
Under the name constitutional mismatch repair-deficiency (CMMR-D), it has been mapped to MLH1, MSH2, MSH6 or PMS2. [2] Monoallelic mutations of these genes are observed in the condition known as Lynch syndrome or hereditary nonpolyposis colorectal cancer, while biallelic mutations are observed in CMMR-D. [3] People expressing the HNPCC (which itself is considered autosomal dominant) trait are ...

DNA mismatch repair protein Mlh1 or MutL protein homolog 1 is a protein that in humans is encoded by the MLH1 gene located on chromosome 3.The gene is commonly associated with hereditary nonpolyposis colorectal cancer.
