Variant summary

Our verdict is Pathogenic. The variant received 20 ACMG points: 20P and 0B. PS3 PM1 PM2 PM5 PP3_Moderate PP5_Very_Strong

The NM_024426.6(WT1):​c.1315C>T​(p.Arg439Cys) 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 Pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV005862888: Experimental studies have shown that this missense change affects WT1 function (PMID:7795587, 22172722).". Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R439H) has been classified as Pathogenic.

Genes affected

WT1 (HGNC:12796): (WT1 transcription factor) This gene encodes a transcription factor that contains four zinc-finger motifs at the C-terminus and a proline/glutamine-rich DNA-binding domain at the N-terminus. It has an essential role in the normal development of the urogenital system, and it is mutated in a small subset of patients with Wilms tumor. This gene exhibits complex tissue-specific and polymorphic imprinting pattern, with biallelic, and monoallelic expression from the maternal and paternal alleles in different tissues. Multiple transcript variants have been described. In several variants, there is evidence for the use of a non-AUG (CUG) translation initiation codon upstream of, and in-frame with the first AUG. Authors of PMID:7926762 also provide evidence that WT1 mRNA undergoes RNA editing in human and rat, and that this process is tissue-restricted and developmentally regulated.

ACMG classification

Our verdict: Pathogenic. The variant received 20 ACMG points.

• PS3: PS3 evidence extracted from ClinVar submissions: SCV005862888: Experimental studies have shown that this missense change affects WT1 function (PMID: 7795587, 22172722).
• PM1: In a hotspot region, there are 5 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 9 uncertain in NM_024426.6
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr11-32392704-C-T is described in ClinVar as Pathogenic. ClinVar VariationId is 3488.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.858
• PP5: Variant 11-32392705-G-A is Pathogenic according to our data. Variant chr11-32392705-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 3505.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
