Name

OPA6 Gene

optic atrophy 6 (autosomal recessive)

OPA4 Gene

optic atrophy 4 (autosomal dominant)

OPA5 Gene

optic atrophy 5 (autosomal dominant)

OPA2 Gene

optic atrophy 2 (obscure)

OPA1 Gene

optic atrophy 1 (autosomal dominant)

The protein encoded by this gene is a nuclear-encoded mitochondrial protein with similarity to dynamin-related GTPases. The encoded protein localizes to the inner mitochondrial membrane and helps regulate mitochondrial stability and energy output. This protein also sequesters cytochrome c. Mutations in this gene have been associated with optic atrophy type 1, which is a dominantly inherited optic neuropathy resulting in progressive loss of visual acuity, leading in many cases to legal blindness.

OPA3 Gene

optic atrophy 3 (autosomal recessive, with chorea and spastic paraplegia)

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]
