NIH Websites Are Changing

Beginning in late July, NIH will start introducing a new website experience designed to make it easier to find health information, research, funding opportunities, and other resources. During the transition, you may notice changes to navigation, page layouts, and where some information is located. Learn more in our Frequently Asked Questions.

Undiagnosed Diseases Network (UDN)

The Undiagnosed Diseases Network (UDN) is a research study that is funded by the National Institutes of Health Common Fund . Its purpose is to bring together clinical and research experts from across the United States to solve the most challenging medical mysteries using advanced technologies.

Through this study, we hope to both help individual patients and families and contribute to the understanding of how the human body works.
