Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4BS2_Supporting
The NM_024426.6(WT1):c.779C>T(p.Ser260Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000173 in 1,613,976 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S260W) has been classified as Uncertain significance.

11p partial monosomy syndrome;C0950121:Drash syndrome;C0950122:Frasier syndrome;CN033288:Wilms tumor 1 Uncertain:1
This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 255 of the WT1 protein (p.Ser255Leu). This variant is present in population databases (no rsID available, gnomAD 0.007%). 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: 543124). 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 tolerated. 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.S255L variant (also known as c.764C>T), located in coding exon 2 of the WT1 gene, results from a C to T substitution at nucleotide position 764. The serine at codon 255 is replaced by leucine, an amino acid with dissimilar properties. This amino acid position is 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. -

not provided Uncertain:1
The WT1 c.779C>T; p.Ser260Leu variant (rs1444869026), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 543124). This variant is only observed on one allele in the Genome Aggregation Database (v2.1.1), indicating it is not a common polymorphism. Computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.4). Due to limited information, the clinical significance of this variant is uncertain at this time. -
