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.

The c.118C>A (p.R40S) alteration is located in exon 1 (coding exon 1) of the P2RX2 gene. This alteration results from a C to A substitution at nucleotide position 118, causing the arginine (R) at amino acid position 40 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
