Description

This sequence change creates a premature translational stop signal (p.Glu262Glyfs*22) 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). This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with MSH2-related conditions. For these reasons, this variant has been classified as Pathogenic.
