Genes affected

P2RX3 (HGNC:8534): (purinergic receptor P2X 3) This gene encodes a member of the P2X purinergic receptor (purinoceptor) gene family which includes seven members (P2RX1 - P2RX7). P2X purinoceptors are a family of cation-permeable, ligand-gated ion channels that open in response to the binding of extracellular adenosine 5'-triphosphate (ATP). The encoded protein is a subunit of the trimeric P2X3 receptor ion channel which is expressed by sensory or autonomic neurons. A deficiency of the orthologous protein in mice is associated with reduced pain-related behavior and urinary bladder hyporeflexia. [provided by RefSeq, Aug 2017]

Jun 30, 2023

The c.83G>T (p.R28L) alteration is located in exon 1 (coding exon 1) of the P2RX3 gene. This alteration results from a G to T substitution at nucleotide position 83, causing the arginine (R) at amino acid position 28 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
