Description

This variant is not present in population databases (ExAC no frequency). For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in MSH6 are known to be pathogenic (PMID: 18269114, 24362816). This variant has not been reported in the literature in individuals with MSH6-related disease. This sequence change creates a premature translational stop signal (p.Glu30Argfs*59) in the MSH6 gene. It is expected to result in an absent or disrupted protein product.
