As they mentioned in their discussion, similar features are reported for coenzyme Q10 deficiency. It is known that 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibition by statins influences not only the cholesterol synthesis but also that of proteins such as farnesylated and geranylgeranylated proteins and ubiquinones such as coenzyme Q10. Similar to cholesterol synthesis, the primary regulation of coenzyme Q10 biosynthesis is the HMG-CoA reductase reaction, providing its isoprenyl side chain deriving from mevalonate. Decreased plasma levels of ...References1. Phillips PS, Haas RH, Bannykh S, Hathaway S, Gray NL, Kimura BJ, . Statin-associated myopathy with normal creatine kinase levels.
