Genes affected

P2RX2 (HGNC:15459): (purinergic receptor P2X 2) The product of this gene belongs to the family of purinoceptors for ATP. This receptor functions as a ligand-gated ion channel. Binding to ATP mediates synaptic transmission between neurons and from neurons to smooth muscle. Multiple transcript variants encoding distinct isoforms have been identified for this gene.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.1388G>A (p.R463Q) alteration is located in exon 10 (coding exon 10) of the P2RX2 gene. This alteration results from a G to A substitution at nucleotide position 1388, causing the arginine (R) at amino acid position 463 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

p.Arg463Gln in exon 10 of P2RX2: This variant is not expected to have clinical s ignificance because the arginine (Arg) residue at position 463 is not conserved through species, with at least 4 mammals (gorilla, chinchilla, brush-tailed rat and horse) having a glutamin (Gln) at this position. It has been identified in 6 /65582 European chromosomes by the Exome Aggregation Consortium (ExAC, http://ex ac.broadinstitute.org; dbSNP rs115260724). -

PreventionGenetics, part of Exact Sciences

Significance:Uncertain significance

Review Status:no assertion criteria provided

Collection Method:clinical testing

The P2RX2 c.1388G>A variant is predicted to result in the amino acid substitution p.Arg463Gln. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0094% of alleles in individuals of European (Non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
