Registry for Patients With WT1 Mutation Associated Diseases

The Wilms' tumor suppressor gene 1 (WT1) encodes for a transcription factor which plays an important role during urogenital development. Patients carrying a WT1 germline mutation show symptoms like proteinuria, Wilms tumors, genital malformations and kidney failure, which usually occur in early childhood. Milder variants are possible and classification as one of the three rare syndromes associated with WT1 mutations (Denys-Drash syndrome, Frasier syndrome or WAGR syndrome) is not always possible. In this registry we are collecting detailed clinical data of affected individuals to establish genotype-phenotype correlations with the greater goal to optimize patient care.
