FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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. Alternative splicing results in multiple transcript variants encoding distinct isoforms. Additional transcript variants have been described, but their full-length natures have not been determined.[provided by RefSeq, Nov 2009]
PHENOTYPE: Homozygotes for targeted null mutations exhibit reduced pairing in meiotic prophase I and produce no mature germ cells. Mutants also display increased microsatellite instability and a predisposition for developing intestinal and other tumors. [provided by MGI curators]
