Undiagnosed Diseases Network (UDN)

The Undiagnosed Diseases Network, funded through NIH Common Fund, is designed to accelerate discovery and innovation in the way we diagnose and treat patients with previously undiagnosed diseases. The specific goals of the network are to: (1) improve the level of diagnosis and care for patients with undiagnosed diseases through the development of common protocols designed by a large community of investigators; (2) facilitate research into the etiology of undiagnosed diseases, by collecting and sharing standardized, high-quality clinical and laboratory data including genotyping, phenotyping, and documentation of environmental exposures; and (3) create an integrated and collaborative community across multiple clinical sites and among laboratory and clinical investigators prepared to investigate the pathophysiology of these new and rare diseases.
