| Gene Variant Descriptions | MLH1 L622H lies within the EXO1-interacting region and C-terminal dimerization domain of the Mlh1 protein (PMID: 22753075). L622H results in decreased Mlh1 protein stability and expression (PMID: 23403630, PMID: 20858721, PMID: 31881334), and demonstrates both proficient mismatch repair (MMR) activity (PMID: 17510385, PMID: 23403630), and deficient MMR activity (PMID: 31881334), and therefore, its effect on Mlh1 protein function is unknown. |
