Myriad Genetics, Inc. RCV002288387 SCV004189055 pathogenic Familial adenomatous polyposis 4 2023-08-29 criteria provided, single submitter clinical testing This variant is considered pathogenic. This variant creates a termination codon and is predicted to result in premature protein truncation.
Labcorp Genetics (formerly Invitae), Labcorp RCV003546755 SCV004268802 pathogenic not provided 2024-03-13 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Lys255*) in the MSH3 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in MSH3 are known to be pathogenic (PMID: 27476653, 37402566). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with MSH3-related conditions. ClinVar contains an entry for this variant (Variation ID: 1709103). For these reasons, this variant has been classified as Pathogenic.
