Labcorp Genetics (formerly Invitae), Labcorp RCV003785324 SCV004603426 uncertain significance Drash syndrome; Frasier syndrome; Wilms tumor 1; 11p partial monosomy syndrome 2024-01-11 criteria provided, single submitter clinical testing This sequence change replaces histidine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 473 of the WT1 protein (p.His473Leu). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with WT1-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. This variant disrupts the p.His473 amino acid residue in WT1. Other variant(s) that disrupt this residue have been observed in individuals with WT1-related conditions (PMID: 15349765, 23302619, 34392242), which suggests that this may be a clinically significant amino acid residue. 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.
