Find Your Condition in the CoRDS Registry

In the United States, the National Institutes of Health defines a rare disease as one that affects fewer than 200,000 people. Some 10,000 rare diseases affect 25 million Americans and 350 million people worldwide.

Dr. David Pearce established Coordination of Rare Diseases at Sanford (CoRDS) after learning the benefits of patient registries on research.

Very few rare diseases have dedicated patient registries. The CoRDS registry serves as a central resource for data on rare diseases to accelerate research into those diseases.

Below are the listed diseases currently in our registry, but we represent all 10,000 rare diseases. You can still participate even if you do not have a disease that is listed below.
