Labcorp Genetics (formerly Invitae), Labcorp RCV003079830 SCV003469938 uncertain significance Drash syndrome; Frasier syndrome; Wilms tumor 1; 11p partial monosomy syndrome 2023-11-19 criteria provided, single submitter clinical testing This sequence change replaces tryptophan, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 328 of the WT1 protein (p.Trp328Arg). This variant is present in population databases (no rsID available, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with WT1-related conditions. ClinVar contains an entry for this variant (Variation ID: 2158450). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on WT1 protein function. 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.
