Nettet17. okt. 2014 · Several neurological syndromes are caused by defective mitochondrial energy production, of which Leigh syndrome is one of the best known. Leigh syndrome is an often fatal, progressive neurodegenerative disorder, first described in 1951 by the British psychiatrist and neuropathologist Denis Leigh (1951). Mutations in mitochondrial DNA (mtDNA) and over 30 genes in nuclear DNA (gene SURF1 and some COX assembly factors) have been implicated in Leigh disease. Disorders of oxidative phosphorylation, the process by which cells produce their main energy source of adenosine triphosphate (ATP), may be caused by mutations in either mtDNA or in nuclear encoded genes. The latter account fo…
