NM_024426.6:c.1211A>C
Variant summary
Our verdict is Uncertain significance. The variant received 3 ACMG points: 4P and 1B. PM1PM2BP4
The NM_024426.6(WT1):c.1211A>C(p.Asn404Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000186 in 1,614,050 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. N404S) has been classified as Uncertain significance.

This sequence change replaces asparagine, which is neutral and polar, with threonine, which is neutral and polar, at codon 399 of the WT1 protein (p.Asn399Thr). This variant is present in population databases (rs748864758, gnomAD 0.0009%). 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: 406697). 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. 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.N399T variant (also known as c.1196A>C), located in coding exon 7 of the WT1 gene, results from an A to C substitution at nucleotide position 1196. The asparagine at codon 399 is replaced by threonine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -
