Center for Rare Kidney Disease


The Department II of Internal Medicine (Nephrology, Rheumatology, Diabetology and General Internal Medicine) provides one of the largest service units for rare kidney diseases in Germany. With a catchment area populated by more than 4 million people we have more than 6000 nephrological outpatient contacts and 900 hospitalizations per year. Our multidisciplinary team offers full medical and psychosocial services. Our center has a special focus on genetic kidney disease in adult patients. Consequently, we see around 500 patients per year suffering from rare and genetic diseases. The clinical service is complemented by a wide range of research activities, which include genetic and experimental research in a dedicated laboratory as well as the participation in and coordination of national and international clinical trials.
