The UT Mitochondrial Center of Excellence, under the direction of Dr. Mary Kay Koenig, is a multidisciplinary center that provides comprehensive care and services to aid in the diagnosis and management of neurometabolic and mitochondrial disorders in both adult and pediatric patients.


  • Our mission is to provide cutting edge medical care to individuals affected by mitochondrial disorder.
  • To perform both clinical and basic science research.
  • To provide treatment options for patients with mitochondrial disease.
  • To educate medical professionals and the community about mitochondrial disease.

Mitochondrial disease occurs when the mitochondria fails to produce enough chemical energy in the form of ATP. Due to this ATP deficiency, it is difficult for many parts of the body, like the brain, muscles and lungs, to function properly. Mitochondrial diseases are inheritable and arise from genetic mutations. We seek to provide exceptional care for our patients and empathize with their family’s concerns. By collaborating with their primary care physician and other medical specialists we provide our patients with the best quality treatment. Each patient is treated with a management plan that is suited to his/her individual needs. Our program conducts world class research to provide cutting edge therapies using a variety of modalities, including: clinical trials, innovative technologies, and personalized INDs (Investigational New Drugs).
