Mitochondrial disease can manifest in many different ways [1] whether in children [2] or adults. [3] Examples of mitochondrial diseases include: Mitochondrial myopathy [2] [3] Maternally inherited diabetes mellitus and deafness (MIDD) [4] While diabetes mellitus and deafness can be found together for other reasons, at an early age this ...
Mitochondrial DNA depletion syndrome (MDS or MDDS), or Alper's disease, is any of a group of autosomal recessive disorders that cause a significant drop in mitochondrial DNA in affected tissues. Symptoms can be any combination of myopathic , hepatopathic , or encephalomyopathic . [ 1 ]
Mitochondrial myopathies are types of myopathies associated with mitochondrial disease. [1] Adenosine triphosphate (), the chemical used to provide energy for the cell, cannot be produced sufficiently by oxidative phosphorylation when the mitochondrion is either damaged or missing necessary enzymes or transport proteins.
Pearson syndrome is a mitochondrial disease characterized by sideroblastic anemia and exocrine pancreas dysfunction. Other clinical features are failure to thrive, pancreatic fibrosis with insulin-dependent diabetes and exocrine pancreatic deficiency, muscle and neurologic impairment, and, frequently, early death. It is usually fatal in infancy.
CPEO is the most common manifestation of mitochondrial myopathy, occurring in an estimated two-thirds of all cases of mitochondrial myopathy. Patients typically present with ptosis (drooping eyelids). Other diseases like Graves' disease, myasthenia gravis and glioma that may cause an external ophthalmoplegia must be ruled out.

Research on mitochondrial dysfunction in Crohn’s disease may have broader implications for understanding other inflammatory and autoimmune diseases, as mitochondrial dysfunction is increasingly ...
MELAS (Mitochondrial Encephalopathy, Lactic Acidosis, and Stroke-like episodes) is one of the family of mitochondrial diseases, which also include MIDD (maternally inherited diabetes and deafness), MERRF syndrome, and Leber's hereditary optic neuropathy.
The mechanism of this condition indicates that the mitochondrial trifunction protein catalyzes 3 steps in mitochondrial beta-oxidation of fatty acids: long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD), long-chain enoyl-CoA hydratase, and long-chain thiolase activities. Trifunctional protein deficiency is characterized by decreased activity of ...
