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.

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Jan 22, 2024	The c.1312G>C (p.D438H) alteration is located in exon 10 (coding exon 10) of the P2RX2 gene. This alteration results from a G to C substitution at nucleotide position 1312, causing the aspartic acid (D) at amino acid position 438 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Uncertain significance, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Jan 03, 2016	The p.Asp438His variant in P2RX2 has not been previously reported in individuals with hearing loss, but has been identified in 1/10176 African chromosomes by th e Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs37 4200273). Computational prediction tools and conservation analysis do not provid e strong support for or against an impact to the protein. In summary, the clinic al significance of the p.Asp438His variant is uncertain. -
