background: Mutant alleles at the BCHE locus are responsible for suxamethonium sensitivity. Homozygous persons sustain prolonged apnea after administration of the muscle relaxant suxamethonium in connection with surgical anesthesia. The activity of pseudocholinesterase in the serum is low and its substrate behavior is atypical. In the absence of the relaxant, the homozygote is at no known disadvantage. [provided by RefSeq, Jul 2008]. Function: Esterase with broad substrate specificity. Contributes to the inactivation of the neurotransmitter acetylcholine. Can degrade neurotoxic organophosphate esters. Subunit: Homotetramer; disulfide-linked. Dimer of dimers. Subcellular Location: Secreted. Tissue Specificity: Detected in blood plasma (at protein level). Present in most cells except erythrocytes. DISEASE: Butyrylcholinesterase deficiency (BChE deficiency) [MIM:177400]: 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. Note=The disease is caused by mutations affecting the gene represented in this entry. Similarity: Belongs to the type-B carboxylesterase/lipase family.
