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.

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 4 of the WT1 protein (p.Pro4Leu). This variant is present in population databases (no rsID available, gnomAD 0.002%). 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: 864517). 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.26C>T; p.Pro9Leu variant (rs948132360), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 864517). This variant is only observed on one allele in the Genome Aggregation Database, indicating it is not a common polymorphism. The proline at codon 9 is weakly conserved, and computational analyses predict that this variant is neutral (REVEL: 0.091). Due to limited information, the clinical significance of this variant is uncertain at this time. -
