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.

Collection Method:clinical testing

The WT1 c.1387C>T (p.Arg463Ter) change is a nonsense variant that is predicted to cause premature protein truncation and loss of normal protein function. This variant has been reported in individuals with Wilms tumor and Denys-Drash syndrome (PMID: 9108089, 19205749, 21851196, 25818337, 31278746, 38110397) where the variant was de novo in at least one individual. This variant is absent in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). In summary, this variant meets criteria to be classified as pathogenic. -

For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 3494). This variant is also known as p.Arg390*. This premature translational stop signal has been observed in individuals with Wilms tumor and Denys-Drash syndrome (PMID: 9108089, 10571943, 12471221, 15150775, 21508141, 21851196, 23117548, 23515051). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Arg458*) in the WT1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in WT1 are known to be pathogenic (PMID: 15150775). -
