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

Nephrotic Syndrome

Nephrotic Syndrome Study Network (NEPTUNE)


NEPTUNE is a study network to improve the identification and management of patients with Nephrotic Syndrome (NS) from Minimal Change Disease (MCD), Focal and Segmental Glomerulosclerosis (FSGS), and Membranous Nephropathy (MN). NEPTUNE includes study sites located at universities and medical facilities across North America and brings together patients, patient advocates, doctors and scientists working together to find better treatments for NS. The network allows experts from many areas to share research information to fast-track results that lead to new discoveries.

An organization led by and dedicated to the Alport community of patients and families.
