Genes affected
BCHE (HGNC:983): (butyrylcholinesterase) This gene encodes a cholinesterase enzyme and member of the type-B carboxylesterase/lipase family of proteins. The encoded enzyme exhibits broad substrate specificity and is involved in the detoxification of poisons including organophosphate nerve agents and pesticides, and the metabolism of drugs including cocaine, heroin and aspirin. Humans homozygous for certain mutations in this gene exhibit prolonged apnea after administration of the muscle relaxant succinylcholine. [provided by RefSeq, Jul 2016]
LINC01322 (HGNC:50528): (long intergenic non-protein coding RNA 1322)

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 14, 2023The c.1330G>A (p.A444T) alteration is located in exon 2 (coding exon 1) of the BCHE gene. This alteration results from a G to A substitution at nucleotide position 1330, causing the alanine (A) at amino acid position 444 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
