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

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.16591814).

BS2

High AC in GnomAd4 at 14 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 110 of the WT1 protein (p.Pro110Ser). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. 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: 406698). 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. -

The WT1 c.328C>T variant is predicted to result in the amino acid substitution p.Pro110Ser. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.042% of alleles in individuals of African descent in gnomAD. This variant is listed in ClinVar as uncertain (https://www.ncbi.nlm.nih.gov/clinvar/variation/406698/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

This variant is located in the WT1 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with WT1-related disorders in the literature. This variant has been identified in 5/114288 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -
