GeneDx RCV000201965 SCV000490620 pathogenic not provided 2017-10-26 criteria provided, single submitter clinical testing This pathogenic variant is denoted MSH6 c.2061T>A at the cDNA level and p.Cys687Ter (C687X) atthe protein level. The substitution creates a nonsense variant, which changes a Cysteine to a premature stop codon(TGT>TGA), 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 an individual with a tubular adenoma and in a Scottish familywith multiple cases of colorectal or Lynch syndrome cancers (Pino 2009, Baglietto 2010), and is consideredpathogenic.

Invitae RCV000530716 SCV000624721 pathogenic Hereditary nonpolyposis colon cancer 2018-07-31 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Cys687*) in the MSH6 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 variant has been observed in an individual affected with Lynch syndrome (PMID: 19324997). ClinVar contains an entry for this variant (Variation ID: 89246). Loss-of-function variants in MSH6 are known to be pathogenic (PMID: 18269114, 24362816). For these reasons, this variant has been classified as Pathogenic.
