Genes affected

P2RX1 (HGNC:8533): (purinergic receptor P2X 1) The protein encoded by this gene belongs to the P2X family of G-protein-coupled receptors. These proteins can form homo-and heterotimers and function as ATP-gated ion channels and mediate rapid and selective permeability to cations. This protein is primarily localized to smooth muscle where binds ATP and mediates synaptic transmission between neurons and from neurons to smooth muscle and may being responsible for sympathetic vasoconstriction in small arteries, arterioles and vas deferens. Mouse studies suggest that this receptor is essential for normal male reproductive function. This protein may also be involved in promoting apoptosis. [provided by RefSeq, Jun 2013]

The c.892G>A (p.V298M) alteration is located in exon 9 (coding exon 9) of the P2RX1 gene. This alteration results from a G to A substitution at nucleotide position 892, causing the valine (V) at amino acid position 298 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
