Clinical Trial Summary

The DiRiP study will enroll patients (n = 3500) with unclear rare diseases and suspected genetic reasons. In group 1 (n = 500) subjects are clinically characterized in the context of outpatient/ inpatient standard care at the UKT or cooperating location, NGS analyzes and other omics analyzes (transcriptomics, proteomics, metabolomics), functional cell biology studies will be performed. In group 2 diagnostics is already performed.

The DiRiP-study fully integrates with the newly formed European Reference Networks (ERNs) for rare diseases, and in particular the ERN-RND, -EURO-NMD, -ITHACA, and -GENTURIS.

Description:

In the DiRiP-RD study (monocentric, prospective, open-label diagnostic study), patients with genetically unexplained diseases will be analyzed or re-analyzed from existing datasets for further omics analysis. These are evaluated with regard to the following questions:

Primary:

• Verification of the genetic causes of unclear genetic diseases

Secondary:

• Improve number of diagnoses of unclear syndromes

• Further characterization of the identified gene defects

• Number of patients receiving appropriate therapy after successful diagnosis. In addition, patient phenotype and genotype data can be collected using a software tool for collecting and analyzing phenotypic information of patients with genetic disorders ( PhenoTips®) software to facilitate data exchange within the UKT, with external collaborators and data transfer to the Solve-RD project.
