Summaries for Leber Optic Atrophy and Dystonia

About this section
NIH Rare Diseases : 54 Leber hereditary optic neuropathy (LHON) with dystonia is a very rare variant of LHON where an individual has LHON associated with dystonia, which involves involuntary muscle contractions, tremors, and other unctrolled movements. It is caused by mutations in one of three mitochondrial genes: MT-ND1, MT-ND3, MT-ND4, and MT-ND6. Other features that have been associated with this condition include difficulty walking, muscle wasting, scoliosis, dysphagia, dysarthria, intellectual disability, dementia, and spasticity. The dystonia usually begins in childhood; vision loss may begin in early adulthood.

MalaCards based summary : Leber Optic Atrophy and Dystonia, also known as leber hereditary optic neuropathy with dystonia, is related to neuropathy and optic nerve disease, and has symptoms including dystonia, bradykinesia and athetosis. An important gene associated with Leber Optic Atrophy and Dystonia is MT-ND4 (Mitochondrially Encoded NADH:Ubiquinone Oxidoreductase Core Subunit 4), and among its related pathways/superpathways are Oxidative phosphorylation and Metabolism. The drugs Idebenone and Protective Agents have been mentioned in the context of this disorder. Affiliated tissues include eye and skeletal muscle, and related phenotypes are abnormality of eye movement and intellectual disability

UniProtKB/Swiss-Prot : 76 Leber hereditary optic neuropathy with dystonia: Part of a spectrum of Leber hereditary optic neuropathy. It is characterized by the association of optic atrophy and central vision loss with dystonia.
