| Impact List | frameshift |
| Protein Effect | unknown |
| Gene Variant Descriptions | MSH2 A913fs results in a change in the amino acid sequence of the Msh2 protein beginning at aa 913 of 934, likely resulting in premature truncation of the functional protein (UniProt.org). A913fs is associated with loss of Msh2 expression in patient samples (PMID: 26674132), but has not been fully biochemically characterized and therefore, its effect on Msh2 protein function is unknown. |
