Rare Diseases Clinical Research Network (RDCRN)

The Rare Diseases Clinical Research Network (RDCRN) is a network of 20 individual clinical research consortia and a Data Management and Coordinating Center (DMCC) funded by the National Institutes of Health (NIH) and led by the National Center for Advancing Translational Sciences. The RDCRN is designed to advance medical research on rare diseases by providing support for clinical studies and facilitating collaboration, study enrollment and data sharing.

Each consortium focuses on at least three related rare diseases or conditions, participates in multisite studies and actively involves patient advocacy groups as research partners. The DMCC enables uniform high-quality data collection and analysis and facilitates information sharing across the network. This robust data source helps scientists better understand the common elements of rare diseases so they may apply that knowledge to improving diagnosis and treatment for these conditions.

Now in its fourth five-year funding cycle, RDCRN is a partnership with funding and programmatic support provided by Institutes, Centers, and Offices across NIH, including the National Institute of Neurological Disorders and Stroke, the National Institute of Allergy and Infectious Diseases, the National Institute of Diabetes and Digestive and Kidney Diseases, the Eunice Kennedy Shriver National Institute of Child Health and Human Development, the National Institute of Arthritis and Musculoskeletal and Skin Diseases, the National Heart, Lung, and Blood Institute, the National Institute of Dental and Craniofacial Research, the National Institute of Mental Health, and the Office of Dietary Supplements.
