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.

The WT1 c.314C>G (p.Ala105Gly) missense change has an over all frequency of 0.058% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). The in silico tool REVEL predicts a benign effect on protein function, but to our knowledge this prediction has not been confirmed by functional studies. This variant has been reported in two siblings with steroid-resistant nephrotic syndrome who were also homozygous for NPHS1 p.Arg586Gly. Notably, their phenotype was more severe than a third sibling who carried only the NPHS1 variant (PMID: 23349334). This variant has also been reported in individuals with breast cancer, primary ovarian insufficiency and disorder of gonadal development (PMID: 35264596, 36099812, 36110220). In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance. -

The p.A100G variant (also known as c.299C>G), located in coding exon 1 of the WT1 gene, results from a C to G substitution at nucleotide position 299. The alanine at codon 100 is replaced by glycine, an amino acid with similar properties. This variant was identified in siblings with congenital nephrotic syndrome and both also had a co-occurring variant in NPHS1 (McCarthy HJ et al. Clin J Am Soc Nephrol, 2013 Apr;8:637-48). This variant was also reported in an Algerian patient with disorder of gonadal development (Zidoune H et al. Front Genet, 2022 Aug;13:900574). This amino acid position is not well conserved in available vertebrate species. 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. -

The WT1 c.299C>G variant is predicted to result in the amino acid substitution p.Ala100Gly. This variant (also described as c.314C>G, p.Ala105Gly in NM_024426.6) has been reported in the homozygous state in a pair of siblings with steroid-resistant nephrotic syndrome (SRNS) who were also apparently homozygous for another missense variant (p.Arg586Gly) in the NPHS1 gene (McCarthy et al. 2013. PubMed ID: 23349334). Of note, both of these individuals were reported to have a more severe phenotype than a third sibling who was also homozygous for the NPHS1 variant but negative for WT1 p.Ala100Gly. The p.Ala100Gly variant has also been observed in the heterozygous state in individuals with various WT1-associated phenotypes including breast cancer (Table S3, Guindalini et al. 2022. PubMed ID: 35264596), primary ovarian insufficiency (Table S7, Heddar et al. 2022. PubMed ID: 36099812), and disorders of sex development (DSD) (Zidoune et al. 2022. PubMed ID: 36110220). This variant is reported in 0.058% of alleles in individuals of Latino descent in gnomAD; however, the quality of this data is questionable and should be treated with caution. This variant is interpreted as uncertain by multiple laboratories in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/476699/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
