Ambry Genetics | RCV000566928 | SCV000673908 | pathogenic | Hereditary cancer-predisposing syndrome | 2021-11-26 | criteria provided, single submitter | clinical testing | The c.1350delT pathogenic mutation, located in coding exon 8 of the MSH2 gene, results from a deletion of one nucleotide at nucleotide position 1350, causing a translational frameshift with a predicted alternate stop codon (p.Q451Rfs*3). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). 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. |

RCV002526912 | SCV003245711 | pathogenic | Hereditary nonpolyposis colorectal neoplasms | 2021-12-11 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 485844). This variant has not been reported in the literature in individuals affected with MSH2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Gln451Argfs*3) in the MSH2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in MSH2 are known to be pathogenic (PMID: 15849733, 24362816). |
