Invitae RCV000629674 SCV000750630 pathogenic Hereditary nonpolyposis colon cancer 2018-09-27 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Ser270*) in the PMS2 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 reported in an individual affected with colorectal cancer (PMID: 25856668) and in individuals with suspected Lynch syndrome (PMID: 28514183). ClinVar contains an entry for this variant (Variation ID: 183732). Loss-of-function variants in PMS2 are known to be pathogenic (PMID: 21376568, 24362816). For these reasons, this variant has been classified as Pathogenic.
GeneDx RCV000657645 SCV000779391 pathogenic not provided 2018-08-16 criteria provided, single submitter clinical testing This pathogenic variant is denoted PMS2 c.809C>G at the cDNA level and p.Ser270Ter (S270X) at the protein level. The substitution creates a nonsense variant, which changes a Serine to a premature stop codon (TCA>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 history of colon cancer and an unaffected individual (Goodenberger 2015, Roberts 2018) and is considered pathogenic.
