Labcorp Genetics (formerly Invitae), Labcorp RCV005094345 SCV005834181 pathogenic not provided 2024-10-30 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 81 of the PAX3 protein (p.Gly81Arg). This variant is present in population databases (rs483353059, gnomAD 0.0009%). This missense change has been observed in individuals with autosomal dominant Waardenburg syndrome (PMID: 20127975, 34142234). ClinVar contains an entry for this variant (Variation ID: 995911). 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 expected to disrupt PAX3 protein function with a positive predictive value of 80%. This variant disrupts the p.Gly81 amino acid residue in PAX3. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 8490648, 9302254, 25991456). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
