The Undiagnosed Diseases Network (UDN) has transitioned from Common Fund leadership. The UDN is now led by The National Institute of Neurological Disorders and Stroke (NINDS). For additional information about the next phase of the UDN, please visit the program’s page on NINDS’ website.

Common Fund makes strategic investments to achieve a set of high-impact goals within a 5-10 year timeframe. At the conclusion of the investment, deliverables may transition to other sources of support or use within the scientific community as UDN has transferred to NINDS. This website is being maintained as an archive and will not be updated on a regular basis.
