This sequence change creates a premature translational stop signal (p.Asn789*) in the MSH6 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in MSH6 are known to be pathogenic (PMID: 18269114, 24362816). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with MSH6-related conditions. For these reasons, this variant has been classified as Pathogenic.

HelpRecord last updated Sep 29, 2024
This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
