Additional findings_Paediatric v0.15 BCHE Zornitza Stark gene: BCHE was added
gene: BCHE was added to Newborn Screening_BabySeq. Sources: Expert list
Mode of inheritance for gene: BCHE was set to BIALLELIC, autosomal or pseudoautosomal
Phenotypes for gene: BCHE were set to Butyrylcholinesterase deficiency, MIM# 617936
Review for gene: BCHE was set to GREEN
Added comment: Individuals deficient in butyrylcholinesterase (BCHE) appear asymptomatic, apart from a heightened sensitivity to muscle relaxants such as suxamethonium (succinylcholine) and mivacurium, 2 BCHE carboxylester substrates. In individuals with usual BCHE levels, these drugs are rapidly hydrolyzed in plasma and their duration of action is short (less than 10 minutes). BCHE deficiency results in slower hydrolysis of these drugs and, consequently, a prolonged neuromuscular block, leading to apnea. Prolonged neuromuscular block occurs with BCHE deficiencies of marked severity (impairment over 70%).
