Registry for Patients With Wilms' Tumor Suppressor Gene 1 (WT1) Mutation Associated Diseases
An observational study of Denys-Drash Syndrome and Frasier Syndrome, run by Universitätsklinikum Hamburg-Eppendorf at 1 site in Germany.
Trial summary
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. Read more about this study

About this study
Official title: 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. Milder variants are possible and classification 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.

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.

Questions about this trial
What is this clinical trial studying?
An observational study of Denys-Drash Syndrome and Frasier Syndrome, run by Universitätsklinikum Hamburg-Eppendorf at 1 site in Germany.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 May 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01252901, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 May 2015.
