| Gene Variant Descriptions | MLH1 D41H lies within the ATPase domain of the Mlh1 protein (PMID: 22753075). D41H results in stable expression of Mlh1, Pms2, Msh2, and Msh6 in patient samples (PMID: 25060679) and variable expression in culture (PMID: 36054288, PMID: 25060679, PMID: 23403630) but leads to loss of mismatch repair activity in in vitro assays (PMID: 23403630, PMID: 25060679), loss of DNA damage response signaling (PMID: 36054288), and microsatellite instability in patient samples (PMID: 25060679). |
