概要    
MELAS syndrome (Mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes) is a maternally inherited multisystem mitochondrial disorder. This disease is associated with mutations in mitochondrial DNA and a biochemical deficiency of respiratory chain complex I. About 80% of MELAS patients have an A3243G mutation in the MTTL1 gene. Other mutations in MTTL1, other mitochondrial tRNA genes, and the mitochondrial MTND subunit genes of complex I have also been reported to cause MELAS.
