Myopathy is a general term for muscle disease and refers in this study to a toxic, drug-induced myopathy with several clinical phenotypes, ranging from muscle symptoms such as pain and weakness to rhabdomyolysis with marked creatine kinase (CK) and myoglobin elevations and sometimes acute renal failure.5 The incidence of rhabdomyolysis is estimated to be as low as 3.4 per 100 000 person-years, but it can be life-threatening.6 Autoimmune necrotizing myopathy is another rare and serious form of myopathy with persisting or progressing of symptoms despite withdrawal of the statin.5 The gene discussed is MB; the disease is myopathy.
