GeneDx	RCV000236121	SCV000292617	pathogenic	not provided	2016-09-21	criteria provided, single submitter	clinical testing	This pathogenic variant is denoted MSH2 c.508C>T at the cDNA level and p.Gln170Ter (Q170X) at the protein level. The substitution creates a nonsense variant, which changes a Glutamine to a premature stop codon (CAG>TAG), and is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. This variant has been reported in multiple individuals with a personal and family history consistent with Lynch syndrome and is considered pathogenic (Mangold 2005, Irmejs 2007, Walsh 2010, Liu 2014).
Invitae	RCV000791416	SCV000548130	pathogenic	Hereditary nonpolyposis colon cancer	2019-06-24	criteria provided, single submitter	clinical testing	This sequence change creates a premature translational stop signal (p.Gln170*) in the MSH2 gene. It is expected to result in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This particular variant has been reported in the literature in individuals affected with Lynch syndrome or Lynch syndrome-associated cancers (PMID: 15849733, 17348456, 24710284, 20215533, 26485756). ClinVar contains an entry for this variant (Variation ID: 91117). Loss-of-function variants in MSH2 are known to be pathogenic (PMID: 15849733, 24362816). For these reasons, this variant has been classified as Pathogenic.
