This sequence change replaces serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 190 of the WT1 protein (p.Ser190Cys). This variant is present in population databases (rs778194188, gnomAD 0.01%). 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: 406700). 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. -
Inborn genetic diseases    Uncertain:1 
The p.S190C variant (also known as c.569C>G), located in coding exon 1 of the WT1 gene, results from a C to G substitution at nucleotide position 569. The serine at codon 190 is replaced by cysteine, an amino acid with dissimilar properties. This amino acid position is not well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. -
Wilms tumor 1    Uncertain:1 
This missense variant replaces serine with cystine at codon 190 in the WT1 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with WT1-related disorders in the literature. This variant has been identified in 3/276284 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -
