Ambry Genetics RCV002421643 SCV002722074 pathogenic Hereditary cancer-predisposing syndrome 2018-09-07 criteria provided, single submitter clinical testing The c.1957delT pathogenic mutation, located in coding exon 11 of the PMS2 gene, results from a deletion of one nucleotide at nucleotide position 1957, causing a translational frameshift with a predicted alternate stop codon (p.C653Vfs*12). This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation.
All of Us Research Program, National Institutes of Health RCV004007381 SCV004844108 pathogenic Lynch syndrome 2023-04-28 criteria provided, single submitter clinical testing This variant deletes 1 nucleotide in exon 11 of the PMS2 gene, creating a frameshift and premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. To our knowledge, this variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). Loss of PMS2 function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic.
