Introduction: Mitochondrial diseases


Mitochondrial diseases: Mitochondrial diseases are very rare. However, they are very interesting because they are genetic diseases, and yet are very different to all other types of genetic disease. Surprisingly, there is actually DNA in the body that is not on any of the 46 chromosomes. This "other DNA" was discovered a long time ago but has only recently been linked to disease. Currently, mitochondrial DNA is an extremely active area of research. See also article Mitochondrial disorders.

Mitochondrial diseases: Mitochondrial myopathies are a group of neuromuscular diseases caused by damage to the mitochondria - small, energy-producing structures found in every cell in the body that serve as the cells' "power plants." Nerve cells in the brain and muscles require a great deal of energy, and thus appear to be particularly damaged when mitochondrial dysfunction occurs. Some of the more common mitochondrial myopathies include Kearns-Sayre syndrome, myoclonus epilepsy with ragged-red fibers (MERRF), and mitochondrial encephalomyopathy lactic acidosis and stroke-like episodes (MELAS). 1

Conditions list: The list of conditions in the Mitochondrial diseases group includes:

Conditions by class: See also the full list of conditions in class genetic.mito.

Researching symptoms of Mitochondrial diseases: Further information about the symptoms of Mitochondrial diseases is available including a list of symptoms of Mitochondrial diseases, other diseases that might have similar symptoms in differential diagnosis of Mitochondrial diseases, or alternatively return to research other symptoms in the symptom center.

Misdiagnosis and Mitochondrial diseases: Research more detailed information about misdiagnosis of Mitochondrial diseases, or research misdiagnosis of other diseases

Treatments for Mitochondrial diseases: Various information is available about treatments available for Mitochondrial diseases, or research treatments for other diseases.
