Beginning March 2022, the Stanford Center for Undiagnosed Diseases will not be accepting new applications until further notice. We are at capacity with our current applicants and participants.

Interested participants and families may still apply to the UDN, but may be assigned to a different clinical site if accepted.

This does not affect patients who are currently enrolled or who have already submitted applications. We will continue our existing research activities to search for diagnoses. Our site is committed to rare disease research and gene discovery.
