Mitochondrial Translation Optimizer-1 Mutation as a Cause of Hereditary Optic Neuropathy

Mitochondrial translation optimizer-1 (MTO1) mutations are a rare cause of hereditary optic neuropathy, with fewer than ten affected families reported in literature. Of these, only one family was reported to have vision loss. We present a case of hereditary optic neuropathy secondary to a mutation in MTO1
