Abstract
- Mitochondrial tRNA(Leu(UUR)) A->G(3243) mutation accounts for 80% of all patients with MELAS(mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes), diabetes mellitus with deafness and progressive external ophthalmoplegia. Optic neuropathy has rarely been reported to be associated with the mutation. We found optic neuropathy in two patients with the mutation. To our knowledge, this is the first case report of optic neuropathy associated with the mutation in Korea.
