Description

This sequence change creates a premature translational stop signal (p.Lys845*) in the MSH2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in MSH2 are known to be pathogenic (PMID: 15849733, 24362816). For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 455568). This variant has not been reported in the literature in individuals affected with MSH2-related conditions. This variant is not present in population databases (gnomAD no frequency).
