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.
Mitochondrial neurogastrointestinal encephalopathy syndrome (MNGIE) is a rare autosomal recessive mitochondrial disease. [2] It has been previously referred to as polyneuropathy, ophthalmoplegia, leukoencephalopathy, and intestinal pseudoobstruction (POLIP syndrome). [3] The disease presents in childhood, but often goes unnoticed for decades.
Mitochondrial encephalopathy is an umbrella term encompassing a variety of disorder that all result from disruptions in mitochondrial function. An overwhelming majority of genes that play a role in mitochondrial function are present within the nuclear DNA, with the remainder (13 proteins, 22 tRNAs, and 2 rRNAs) being encoded by the ...
About 1 in 4,000 children in the United States will develop mitochondrial disease by the age of 10 years. Up to 4,000 children per year in the US are born with a type of mitochondrial disease. [ 44 ] Because mitochondrial disorders contain many variations and subsets, some particular mitochondrial disorders are very rare.
Pearson syndrome is a mitochondrial disease caused by a deletion in mitochondrial DNA (mtDNA). [3] An mtDNA is genetic material contained in the cellular organelle called the mitochondria. Depending on the tissue type, each cell contains hundreds to thousands of mitochondria. There are 2–10 mtDNA molecules in each mitochondrion.
Leigh syndrome was first described by Denis Leigh in 1951 [21] and distinguished from similar Wernicke's encephalopathy in 1954. [9] In 1968, the disease's link with mitochondrial activity was first ascertained, though the mutations in cytochrome c oxidase and other electron transport chain proteins were not discovered until 1977. [7]
Neuropathy, ataxia, and retinitis pigmentosa, also known as NARP syndrome, is a rare disease with mitochondrial inheritance that causes a variety of signs and symptoms chiefly affecting the nervous system [1] Beginning in childhood or early adulthood, most people with NARP experience numbness, tingling, or pain in the arms and legs (sensory neuropathy); muscle weakness; and problems with ...
Mitochondrial encephalopathy: Metabolic disorder caused by dysfunction of mitochondrial DNA. Can affect many body systems, particularly the brain and nervous system. Acute necrotizing encephalopathy, rare disease that occurs following a viral infection. Glycine encephalopathy: A genetic metabolic disorder involving excess production of glycine.
