Genes affected

P2RX5 (HGNC:8536): (purinergic receptor P2X 5) The product of this gene belongs to the family of purinoceptors for ATP. This receptor functions as a ligand-gated ion channel. Alternative splicing results in multiple transcript variants. Read-through transcription also exists between this gene and the neighboring downstream gene, TAX1BP3 (Tax1 binding protein 3). [provided by RefSeq, Mar 2011]

P2RX5-TAX1BP3 (HGNC:49191): (P2RX5-TAX1BP3 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring P2RX5 (purinergic receptor P2X, ligand-gated ion channel, 5) and TAX1BP3 (Tax1 binding protein 3) genes on chromosome 17. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus unlikely to produce a protein product. [provided by RefSeq, Mar 2011]

ACMG classification

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP7: Synonymous conserved (PhyloP=3.03 with no splicing effect.
