About Us
Description
The Undiagnosed Diseases Network (UDN) is a research study funded by the National Institutes of Health. 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 living with the burden of undiagnosed diseases, and contribute to the understanding of how the human body works.
Sites
The UDN is made up of a Data Management Coordinating Center, Clinical Sites, and Core Facilities.
The Data Management Coordinating Center, which coordinates the work of the UDN, is based at Harvard Medical School, Morehouse School of Medicine, University of Alabama at Birmingham, University of Utah, Washington University in St. Louis, and Stanford University.
The Clinical Sites, where UDN participants are evaluated, are located in 15 locations across the United States:

At the Clinical Sites, doctors and healthcare providers, like neurologists, immunologists, nephrologists, endocrinologists, and geneticists, work together to help find the cause of participant symptoms.
The Sequencing Core, which provides sequencing services for the UDN, is at Baylor College of Medicine.
The Model Organisms Screening Center, located at Baylor College of Medicine, Washington University in St. Louis, and University of Oregon, helps the network understand how specific genetic changes contribute to disease by studying these changes in other organisms. The Metabolomics Core, located at the Mayo Clinic in Rochester, MN, provides the UDN with advanced tools to study biological markers that might be related to disease.
