Variant summary

Our verdict is Pathogenic. Variant got 13 ACMG points: 13P and 0B. PM2 PM5 PP3 PP5_Very_Strong

The NM_024426.6(WT1):​c.1405G>T​(p.Asp469Tyr) 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. D469G) 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

Verdict is Pathogenic. Variant got 13 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr11-32392013-T-C is described in Lovd as [Pathogenic].
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.835
• PP5: Variant 11-32392014-C-A is Pathogenic according to our data. Variant chr11-32392014-C-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 547167.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

The WT1 c.1390G>T variant is predicted to result in the amino acid substitution p.Asp464Tyr. This variant has been reported in an individual with early onset Denys Drash syndrome (reported as D396Y, Little et al. 2000. PubMed ID: 10738002). This variant has also been reported as a de novo variant in an individual with WT1-related nephropathy and in an individual from a cohort of pediatric patients with segmental glomerulosclerosis and focal segmental glomerulosclerosis (SRNS/FSGS) with end-stage renal disease (ESRD)(Table S4, Mestek-Boukhibar et al. 2018. PubMed ID: 30049826; reported as D469Y, Supplementary Table S2, Park et al. 2020. PubMed ID: 32604935). Other variants affecting the same amino acid (Asp464) have been reported in individuals with Denys Drash Syndrome/Nephrotic Syndrome (reported as Asp396His, Hakan et al. 2012. PubMed ID: 22876585; reported as Asp396Gly and Asp396Asn, Pelletier et al. 1991. PubMed ID: 1655284; reported as D396N, Table 3, Li et al. 2010. PubMed ID: 20442690). This variant has not been reported in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. Taken together, the WT1 c.1390G>T (p.Asp464Tyr) variant is interpreted as pathogenic. -
