  Aims: The 3243A>G mutation of mtDNA usually is associated with MELAS syndrome.In 3243A>G patients, respiratory chain complex Ⅰ deficiency is most frequently found, and partial decreased amounts of complexes Ⅲ and Ⅳ.We report a case of a patient with combined defects of complexs Ⅰ and Ⅲ, and analyze the influence of enzyme activity dysfunction due to 3243 A>G mutation.
