Summaries for Leber Optic Atrophy

About this section
MalaCards based summary : Leber Optic Atrophy, also known as leber optic atrophy, susceptibility to, is related to leber optic atrophy and dystonia and leber hereditary optic neuropathy, and has symptoms including ataxia and static tremor. An important gene associated with Leber Optic Atrophy is LOAS (Leber Optic Atrophy, Susceptibility To), and among its related pathways/superpathways are Metabolism and Respiratory electron transport, ATP synthesis by chemiosmotic coupling, and heat production by uncoupling proteins.. The drugs Idebenone and Protective Agents have been mentioned in the context of this disorder. Affiliated tissues include eye and temporal lobe, and related phenotypes are optic atrophy and leber optic atrophy
