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.
