Protein Effect | unknown |
Gene Variant Descriptions | MLH1 K618T lies within the EXO1-interacting region and C-terminal dimerization domain of the Mlh1 protein (PMID: 22753075). The functional effect of K618T is conflicting, as it has been shown to have mismatch repair activity and Pms2 binding similar to wild-type Mlh1 (PMID: 16083711, PMID: 22753075, PMID: 21120944), but has also been shown to have significantly reduced binding to Pms2 in in vitro assays (PMID: 10037723), and decreases MLH1 foci and chromosomal crossover during meiosis resulting in increased aneuploidy in a mouse model (PMID: 34408140), and therefore, its effect on Mlh1 protein function is unknown. |
