Labcorp Genetics (formerly Invitae), Labcorp RCV001544558 SCV000544228 uncertain significance not provided 2025-02-02 criteria provided, single submitter clinical testing This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 41 of the POLE protein (p.Thr41Met). This variant is present in population databases (rs148269473, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with POLE-related conditions. ClinVar contains an entry for this variant (Variation ID: 405900). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt POLE protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
GeneDx RCV001544558 SCV001763713 uncertain significance not provided 2023-12-29 criteria provided, single submitter clinical testing In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
PreventionGenetics, part of Exact Sciences RCV004539937 SCV004783047 uncertain significance POLE-related disorder 2024-01-31 no assertion criteria provided clinical testing The POLE c.122C>T variant is predicted to result in the amino acid substitution p.Thr41Met. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.035% of alleles in individuals of East Asian descent in gnomAD and it is interpreted as uncertain in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/405900/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
