MutL homolog 1, colon cancer, nonpolyposis type 2 (E. coli), also known as MLH1, is a human gene. MLH1 is a gene commonly associated with hereditary nonpolyposis colorectal cancer.


This gene was identified as a locus frequently mutated in hereditary nonpolyposis colon cancer (HNPCC). It is a human homolog of the E. coli DNA mismatch repair gene mutL, consistent with the characteristic alterations in microsatellite sequences (RER+ phenotype) found in HNPCC. Alternatively spliced transcript variants encoding different isoforms have been described, but their full-length natures have not been determined.[1]


It can also be associated with Turcot syndrome.
