The Rare Diseases Clinical Research Network is an NIH-funded research network of 20 active consortia or research groups working to advance treatment for diseases that are rare. Use the search tools on this page to find the diseases we currently study. You can reach out to the indicated consortia or research groups for more information on those diseases and studies underway.
This network focuses on clinical research and does not generally support clinical care outside of research activities. To learn about other rare diseases, please visit the Genetic and Rare Diseases Information Center (GARD), which is an NIH program that helps the public find reliable information about rare and genetic diseases. Their staff are specialists. Contact them at 1-888-205-2311 or email GARDinfo@nih.gov.

Diabetes and Deafness (DAD)
Alternative Names: Maternally Inherited Diabetes and Deafness (MIDD); Ballinger Wallace Syndrome; Diabetes Mellitus Type II with Deafness
Disease Category: Mitochondrial Disorders
A rare, mitochondrial (referring to specialized cell structures that produce energy) disorder characterized by hearing loss, especially of high tones, and hyperglycemia (high blood glucose levels) due to diabetes mellitus. The disorder is caused by mutations in the DNA of mitochondria (specialized cell structures that produce energy). Because the mitochondrial DNA mutation is inherited from mothers, it is a maternally inherited disorder. Onset of hearing loss usually occurs before diabetes, typically in mid-adulthood.
