Brief Summary

In the DISCO-TWIN study (prospective, open-label molecular-genetic study), twin pairs with one healthy and one affected twin with molecularly undiagnosed diseases will be analysed by means of omics technologies and/ or re-analysed using existing datasets. Phenotype and omics data will be shared within the University Hospital Tübingen and with external collaborators to improve the diagnostic rate of the subjects included in the study.
