Description

This sequence change deletes 2 nucleotides in exon 12 of the MSH2 mRNA (c.1963_1964delGT), causing a frameshift at codon 655. This creates a premature translational stop signal (p.Val655Ilefs*3) and is expected to result in an absent or disrupted protein product. While this particular variant has not been reported in the literature, truncating variants in MSH2 are known to be pathogenic (PMID: 15849733, 24362816). For these reasons, this variant has been classified as Pathogenic.
