Our verdict is Benign. The variant received -12 ACMG points: 0P and 12B. BP4_Strong BA1

The NM_002562.6(P2RX7):​c.463T>C​(p.Tyr155His) variant causes a missense change. The variant allele was found at a frequency of 0.552 in 1,613,226 control chromosomes in the GnomAD database, including 249,150 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Y155N) has been classified as Uncertain significance.

Genes affected

P2RX7 (HGNC:8537): (purinergic receptor P2X 7) The product of this gene belongs to the family of purinoceptors for ATP. This receptor functions as a ligand-gated ion channel and is responsible for ATP-dependent lysis of macrophages through the formation of membrane pores permeable to large molecules. Activation of this nuclear receptor by ATP in the cytoplasm may be a mechanism by which cellular activity can be coupled to changes in gene expression. Multiple alternatively spliced variants have been identified, most of which fit nonsense-mediated decay (NMD) criteria. [provided by RefSeq, Jul 2010]

ENSG00000295862 (HGNC:):

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=1.8173456E-4).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.692 is higher than 0.05.
