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.

Likely benign, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJun 28, 2017p.Glu481Lys in exon 10B of P2RX2: This variant is not expected to have clinical significance due to a lack of conservation across species, including mammals. Of note, at least 3 mammals have a lysine (Lys) at this position. In addition, com putational prediction tools do not suggest a high likelihood of impact to the pr otein. It has also been identified in 0.1% (20/34408) of Latino chromosomes by t he Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs199955493). -
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 09, 2021The c.1441G>A (p.E481K) 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 1441, causing the glutamic acid (E) at amino acid position 481 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
