Variant | Y750* |
Impact List | nonsense |
Protein Effect | loss of function - predicted |
Gene Variant Descriptions | MLH1 Y750* results in a premature truncation of the Mlh1 protein at amino acid 750 of 756 (UniProt.org). Y750* demonstrates expression levels similar to wild-type Mlh1 (PMID: 20533529) but results in a loss of the C-terminal domain, demonstrates decreased stability of the Mlh1/Pms2 heterodimer (PMID: 16338176), leads to reduced Pms2 expression in culture, and reduced mismatch repair activity in an in vitro assay (PMID: 20533529), and therefore, is predicted to lead to a loss of Mlh1 protein function. |
