OPA1 Gene Information

HGNC symbol
OPA1 
Aliases
FLJ12460; KIAA0567; MGM1; NPG; NTG 
Common name
OPA1 mitochondrial dynamin like GTPase 
Entrez Id
4976
Description
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.
