Labcorp Genetics (formerly Invitae), Labcorp RCV001227903 SCV001400282 uncertain significance Drash syndrome; Frasier syndrome; Wilms tumor 1; 11p partial monosomy syndrome 2019-10-29 criteria provided, single submitter clinical testing 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The leucine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with WT1-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This sequence change replaces histidine with leucine at codon 16 of the WT1 protein (p.His16Leu). The histidine residue is weakly conserved and there is a moderate physicochemical difference between histidine and leucine.
