Ambry Genetics RCV000490843 SCV000580273 pathogenic Hereditary cancer-predisposing syndrome 2015-03-31 criteria provided, single submitter clinical testing Lines of evidence used in support of classification: Other acmg-defined mutation (i.e. initiation codon or gross deletion)
GeneDx RCV000657749 SCV000779501 pathogenic not provided 2018-01-12 criteria provided, single submitter clinical testing This variant is denoted MSH6 c.1243C>T at the cDNA level and p.Gln415Ter (Q415X) 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 an individual with colorectal cancer (Morak 2017) and is considered pathogenic.
Invitae RCV000812630 SCV000952950 pathogenic Hereditary nonpolyposis colon cancer 2018-08-15 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Gln415*) 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 colon cancer (PMID: 28528517). ClinVar contains an entry for this variant (Variation ID: 428378). Loss-of-function variants in MSH6 are known to be pathogenic (PMID: 18269114, 24362816). For these reasons, this variant has been classified as Pathogenic.
