Genes affected

P2RX4 (HGNC:8535): (purinergic receptor P2X 4) The product of this gene belongs to the family of purinoceptors for ATP. This receptor functions as a ligand-gated ion channel with high calcium permeability. The main pharmacological distinction between the members of the purinoceptor family is the relative sensitivity to the antagonists suramin and PPADS. The product of this gene has the lowest sensitivity for these antagonists. Multiple alternatively spliced transcript variants, some protein-coding and some not protein-coding, have been found for this gene. [provided by RefSeq, Feb 2012]

Ambry Genetics

May 01, 2024

The c.448G>A (p.V150I) alteration is located in exon 5 (coding exon 5) of the P2RX4 gene. This alteration results from a G to A substitution at nucleotide position 448, causing the valine (V) at amino acid position 150 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
