MITOPATH SLThrough development of a novel gene therapy treatment, MitoPath is dedicated to helping patients living with MNGIE take back their future.
Mitochondrial NeuroGastroIntestinal Encephalomyopathy or MNGIE, is a rare autosomal recessive mitochondrial disease. People living with MNGIE have a mutation in their DNA where they have low to no expression of a protein called thymidine phosphorylase or TYMP gene.
Having low to no TYMP protein indirectly leads to the incorporation of mutations in the mitochondrial DNA. As time goes on, more mutations are incorporated until the mitochondria are unable to carry out their normal functions.
The disease’s symptoms become apparent around puberty, but the accurate diagnosis of the disease is often delayed by 6 – 8 years due to it being commonly misdiagnosed as any of the following: anorexia nervosa, MELAS, MERRF, inflammatory bowel disease, superior mesenteric artery syndrome, Whipple disease, chronic intestinal pseudo-obstruction, chronic inflammatory demyelinating polyneuropathy or Charcot Marie Tooth disease. Individuals with MNGIE have extremely low weight, and their first symptoms tend to be neurologic. As the disease progresses, the function of the gastrointestinal system is impaired, leading to the most severe symptoms and eventually resulting in death in ~85% of cases by age 40.
