A Look at Genetic Linkage between Clozapine-induced Agranulocytosis, Malignant Hyperthermia, Neuroleptic Malignant Syndrome, and Statin-induced Myopathy.

Clozapine-induced agranulocytosis, malignant hyperthermia (MH), statin-induced myopathy, and neuroleptic malignant syndrome (NMS) are all serious drug reactions with significant overlap in terms of clinical symptomatology. The use of clozapine can lead to neutropenia, as well as the development of NMS; thus, it seemed logical to explore a possible common genetic background for the development of these two adverse effects. Furthermore, due to the overwhelming clinical resemblance between NMS, MH, and statin-induced myopathy, we decided specifically to search for a common genetic background in the development of these conditions.
