Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 1P and 5B. PP5BP4BS2

The NM_000055.4(BCHE):​c.1253G>T​(p.Gly418Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00403 in 1,613,898 control chromosomes in the GnomAD database, including 18 homozygotes. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G418A) has been classified as Uncertain significance.

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

Classification was made for transcript

Our verdict: Likely_benign. The variant received -4 ACMG points.

PP5
Variant 3-165829781-C-A is Pathogenic according to our data. Variant chr3-165829781-C-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 13219.
BP4
Computational evidence support a benign effect (MetaRNN=0.01191321). . Strength limited to SUPPORTING due to the PP5.
BS2
High Homozygotes in GnomAdExome4 at 17 AR,Unknown gene
