Abstract
- The 14484 mutation in the ND6 gene of mitochondrial DNA (mtDNA) is a genetic mutation associated with Leber's hereditary optic neuropathy (LHON) in Caucasian patients who show a high incidence of visual recovery. We evaluated four Japanese patients with LHON associated with the 14484 mutation who were negative for eight proposed secondary mutations. There was no family history of optic atrophy in three of the four patients. All four patients were initially diagnosed as having optic neuritis, either anterior (Cases 1 and 3) or retrobulbar (Cases 2 and 4), based upon their fundus findings and clinical history. Molecular genetic testing of mtDNA confirmed the diagnosis of LHON in all four patients. The three patients who experienced recovery had their vision return to 20/50 or better in both eyes. The patient who did not was a heavy consumer of alcohol and tobacco. These findings indicate that Japanese patients with the 14484 mutation have a visual prognosis similar to that of Caucasians with this mutation.
