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)

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.03).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.909 is higher than 0.05.
