Leigh disease

Leigh dis·ease

(lē), [MIM*256000] a rare fatal mitochondrial disorder affecting principally infants and young children, manifested as seizures, psychomotor retardation, spasticity, myoclonus, optic atrophy, cranial nerve palsies, and ataxia; due to deficiencies of cytochrome c oxidase or NADH-ubiquinone oxidoreductase or other enzymes involved in energy metabolism; pathologically, there is widespread symmetric necrosis; most often autosomal recessive transmisstion, but X-link recessive and mitochondrial inheritances have been described. Synonym(s): Leigh syndrome, necrotizing encephalomyelopathy, necrotizing encephalopathy, subacute necrotizing encephalomyelopathy

Leigh dis·ease

(lā di-zēz') Subacute encephalomyelopathy affecting infants, causing seizures, spasticity, optic atrophy, and dementia; the genetic causation is heterogeneous; may be associated with deficiency of cytochrome c oxidase or nicotinamide adenine dinucleotide (reduced form)-ubiquinone oxidoreductase or other enzymes involved in energy metabolism. Autosomal recessive, X-linked recessive and mitochondrial inheritance have been described; mutations have been identified in the surfeit-1 gene (SURF) on chromosome 9, in a mtDNA-encoded subunit of adenosine triphosphate synthase, in the X-linked E1-alpha subunit of pyruvate dehydrogenase, and in several subunits of mitochondrial complex I.
