Autoantibodies to HMG-CoA reductase are notably absent in patients with self-limited, non-autoimmune forms of statin myopathy, thus an alternative Immune-mediated myopathy related to anti 3-hydroxy-3-methylglutaryl-coenzyme A reductase antibodies as an emerging cause of necrotizing myopathy induced by statins.
