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.

Variant classified as Uncertain Significance - Favor Benign. The c.906-13G>A var iant in P2RX2 has not been previously reported in individuals with hearing loss, but has been identified in 2/8652 of East Asian chromosomes by the Exome Aggreg ation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs757748091). Alth ough this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. This variant is located in the 3' spl ice region. Computational tools do not suggest an impact to splicing. However, t his information is not predictive enough to rule out pathogenicity. In summary, while the clinical significance of the c.906-13G>A variant is uncertain, these d ata suggest that it is more likely to be benign. -
