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.

IgA vasculitis
Alternative Names: Henoch-Schonlein purpura, Immunoglobulin A Vasculitis
Disease Category: Vasculitis Disorders
A rare, immune system disorder characterized by accumulation of immunoglobulin A (a specific antibody protein) in small blood vessels. This causes inflammation and leakage of blood, affecting the skin, joints, digestive tract, kidneys, and, rarely, the nervous system and lungs. The most common symptom is purpura (a red or purple skin rash). Severe cases may lead to acute kidney injuries that progress to chronic kidney disease.
