Genes affected
P2RX6 (HGNC:8538): (purinergic receptor P2X 6) The protein encoded by this gene belongs to the family of P2X receptors, which are ATP-gated ion channels and mediate rapid and selective permeability to cations. This gene is predominantly expressed in skeletal muscle, and regulated by p53. The encoded protein is associated with VE-cadherin at the adherens junctions of human umbilical vein endothelial cells. Alternative splicing results in multiple transcript variants. A related pseudogene, which is also located on chromosome 22, has been identified. [provided by RefSeq, Apr 2009]

Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.718G>A (p.V240M) alteration is located in exon 7 (coding exon 7) of the P2RX6 gene. This alteration results from a G to A substitution at nucleotide position 718, causing the valine (V) at amino acid position 240 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
