Undiagnosed Diseases

The Vanderbilt Undiagnosed Diseases Program exists to solve medical mysteries for patients with complicated conditions and rare diseases. Our goal is to provide answers and offer hope to adults and children whose symptoms have not led other health care providers to solutions. Our patients benefit from a team approach involving experts from across Vanderbilt University Medical Center.
