The Rare Diseases Clinical Research Network (RDCRN) is an NIH-funded research network of 23 active consortia or research groups—teams of researchers, patients and clinicians—each focused on a group of rare disorders. Use the search tools on this page to find the diseases we currently study and reach out to the indicated consortia or research groups for more information on those diseases.

This network focuses on clinical research and does not generally support clinical care outside of research activities. To learn about other rare diseases, please visit the Genetic and Rare Diseases Information Center (GARD), which is an NIH program that helps the public find reliable information about rare and genetic diseases. Their staff are specialists. Contact them at 1-888-205-2311 or email
