Variant summary
Our verdict is Pathogenic. Variant got 16 ACMG points: 16P and 0B. PM1PM2PM5PP3_ModeratePP5_Very_Strong
The NM_024426.6(WT1):c.1348C>T(p.His450Tyr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. H450R) has been classified as Likely pathogenic.

Drash syndrome Pathogenic:2
Likely pathogenic, criteria provided, single submitter | clinical testing | Neuberg Centre For Genomic Medicine, NCGM | - | The missense variant p.H450Y in WT1 (NM_024426.6) chas been reported previously as His377Tyr in an affected patient with Denys Drasch syndrome (Jeanpierre, C et al). The variant has been submitted to ClinVar as Pathogenic but no functional studies have been reported. The p.H450Y variant is novel (not in any individuals) in gnomAD Exomes and is novel (not in any individuals) in 1000 Genomes. The p.H450Y missense variant is predicted to be damaging by both SIFT and PolyPhen2. The histidine residue at codon 450 of WT1 is conserved in all mammalian species. The nucleotide c.1348 in WT1 is predicted conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Likely Pathogenic. - |

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Oct 09, 2022 | This sequence change replaces histidine, which is basic and polar, with tyrosine, which is neutral and polar, at codon 445 of the WT1 protein (p.His445Tyr). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of Denys-Drash syndrome (PMID: 1327525, 9529364). In at least one individual the variant was observed to be de novo. This variant is also known as His377Tyr. ClinVar contains an entry for this variant (Variation ID: 3495). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. This variant disrupts the p.His445 amino acid residue in WT1. Other variant(s) that disrupt this residue have been observed in individuals with WT1-related conditions (PMID: 20562648, 21851196), which suggests that this may be a clinically significant amino acid residue. For these reasons, this variant has been classified as Pathogenic. - |
