[[http://www.uniprot.org/uniprot/CHLE_HUMAN CHLE_HUMAN]] Defects in BCHE are the cause of butyrylcholinesterase deficiency (BChE deficiency) [MIM:[http://omim.org/entry/177400 177400]]. BChE deficiency is a metabolic disorder characterized by prolonged apnoea after the use of certain anesthetic drugs, including the muscle relaxants succinylcholine or mivacurium and other ester local anesthetics. The duration of the prolonged apnoea varies significantly depending on the extent of the enzyme deficiency. BChE deficiency is a multifactorial disorder. The hereditary condition is transmitted as an autosomal recessive trait.
