Abstract
The guanine-to-adenine substitution at nucleotide 1606 (G1606A) mutation in the mitochondrial DNA transfer RNA–valine gene has been reported to cause sensorineural deafness, ataxia, myoclonus, seizures, and mental retardation. This study hereby presents a single case report of a new retinal phenotype associated with this mutation: a middle-aged woman with retinal pigment epithelium stippling, atrophy, and peripapillary (retinal pigment epithelium) dropout on fundus examination. The patient was administered an empiric trial of a mitochondrial cocktail with close monitoring of her systemic symptoms. This study identified a novel G1606A mutation to cause early-onset macular pathology resembling that previously described in the A3243G mutation.
