Who We Are
The RDCRN program is designed to advance medical research on rare diseases by providing support for clinical studies and facilitating collaboration, study enrollment and data sharing. Through the RDCRN consortia, physician scientists and their multidisciplinary teams work together with patient advocacy groups to study nearly 200 rare diseases at sites across the nation.

Training the Next Generation of Researchers
Our consortia place a high priority on the recruitment, training and support of early career researchers due to the significant need for well-trained clinical researchers in the rare diseases field.
Find OpportunitiesInformation for Patients and Families
Our network focuses on clinical research and does not generally support clinical care outside research activities. View the diseases that we currently study here.
If you are looking for information on rare diseases not currently studied by the RDCRN, visit the NIH’s Genetic and Rare Diseases Information Center (GARD), which helps the public find reliable information about rare and genetic diseases. Contact their specialists at 888-205-2311 or email GARDinfo@nih.gov.
NIH Funding Institutes, Centers, and Offices
