| Gene Variant Descriptions | MLH1 L749P does not lie within any known functional domains of the Mlh1 protein (UniProt.org). L749P results in expression levels similar to wild-type Mlh1 in culture in one study (PMID: 20533529) but in another study results in reduced Mlh1 expression in culture (PMID: 22736432), and results in decreased Pms2 expression and deficient mismatch repair (MMR) activity in cultured cells (PMID: 20533529, PMID: 22736432), and therefore, is predicted to lead to a loss of Mlh1 protein function. |
