Entrez Gene Summary for OPA3 Gene

  • The mouse ortholog of this protein co-purifies with the mitochondrial inner membrane. Mutations in this gene have been shown to result in 3-methylglutaconic aciduria type III and autosomal dominant optic atrophy and cataract. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2009]

Disorders for OPA3 Gene

(2) OMIM Diseases for OPA3 Gene (606580)


  • 3-methylglutaconic aciduria 3 (MGA3) [MIM:258501]: A metabolic disorder that causes a neuro-ophthalmologic syndrome consisting of early-onset bilateral optic atrophy, spasticity, extrapyramidal dysfunction and cognitive deficit. Urinary excretion of 3-methylglutaconic acid and 3-methylglutaric acid is increased. MGA3 can be distinguished from MGA1 by the absence of increase of 3-hydroxyisovaleric acid levels. {ECO:0000269 PubMed:11668429}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Optic atrophy 3 (OPA3) [MIM:165300]: A condition that features progressive visual loss in association with optic atrophy. Atrophy of the optic disk indicates a deficiency in the number of nerve fibers which arise in the retina and converge to form the optic disk, optic nerve, optic chiasm and optic tracts. OPA3 is associated with cataract and a neurologic disorder characterized by extrapyramidal signs and ataxia. {ECO:0000269 PubMed:15342707}. Note=The disease is caused by mutations affecting the gene represented in this entry.
