WT1 and Wilms tumor: An analysis of ClinVar (https://www.ncbi.nlm.nih.gov/clinvar) for pathogenic variants involving the ZF4 of WT1 indicated several missense variants (p.Pro487Ser, Variation ID: 543123; p.Ser488Asn [x2], Variation ID: 578607; p.Lys491Arg, Variation ID: 655847; p.His505Gln, Variation ID: 664113) in association with the typical clinical features of WT1 pathogenic variants (Denys–Drash syndrome, Wilms tumor, aniridia, genitourinary anomalies, mental retardation syndrome, Frasier syndrome).
