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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJul 20, 2017The p.Leu390Val variant in P2RX2 has not been previously reported in individuals with hearing loss but has been identified in 1/33508 Latino chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs7 49812549). Although this variant has been seen in the general population, its fr equency is not high enough to rule out a pathogenic role. Computational predicti on tools and conservation analyses do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Leu390V al variant is uncertain. -
