Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3

The NM_002561.4(P2RX5):c.997G>C(p.Asp333His) variant causes a missense change. The variant allele was found at a frequency of 0.0000732 in 1,612,980 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D333E) has been classified as Uncertain significance.

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 links:

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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.997G>C (p.D333H) alteration is located in exon 10 (coding exon 10) of the P2RX5 gene. This alteration results from a G to C substitution at nucleotide position 997, causing the aspartic acid (D) at amino acid position 333 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
