Diseases Studied

The Rare Diseases Clinical Research Network is an NIH-funded research network of 20 active consortia or research groups working to advance treatment for diseases that are rare. Use the search tools on this page to find the diseases we currently study. You can reach out to the indicated consortia or research groups for more information on those diseases and studies underway.

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 GARDinfo@nih.gov.

Primary Ciliary Dyskinesia (PCD)

Disease Category: Genetic Mucociliary Disorders

An inherited condition in which mucociliary clearance of the lungs is impaired. In this disorder, cilia (hairlike structures) lining the airway, sinuses, and middle ears have defective movements, leading to accumulation of harmful particles and pathogens trapped within mucus. This results in chronic sinusitis, and frequent respiratory and middle ear infections. These recurrent infections may lead to hearing loss, chronic cough, severe lung damage, and bronchiectasis (irreversible scarring and dilation of the bronchi).
