rs208294
Variant in the P2RX7 gene (Purinergic Receptor P2X 7)
rs208294 is a single nucleotide polymorphism (SNP) in the P2RX7 gene, involved in ATP danger signal / NLRP3 inflammasome activation. Variants at this position have been studied in relation to immune function, metabolism, and chronic illness.

What is the rs208294 variant?
rs208294 is a SNP (single nucleotide polymorphism) in the P2RX7 (Purinergic Receptor P2X 7) gene. It belongs to the Immune Signaling category and is part of the Immune System & Inflammation biological cluster. P2RX7 encodes the P2X7 ATP receptor on macrophages and microglia, which activates the NLRP3 inflammasome upon extracellular ATP binding.
Biological role and pathway
This variant sits within the P2RX7 gene, which is involved in the ATP danger signal / NLRP3 inflammasome activation pathway. Genes within the Immune System & Inflammation cluster work together to maintain balanced function across interconnected biological systems.
Variants in genes within this pathway may influence an individual's predisposition to altered function — particularly under conditions of physiological stress such as viral infection or prolonged illness.
rs208294 and Long COVID / ME-CFS research
P2RX7-NLRP3 inflammasome activation by extracellular ATP (released from damaged cells) drives IL-1beta secretion; variants (Arg307Gln loss-of-function) may affect inflammasome-driven inflammation in Long COVID.

Frequently asked questions
What is the rs208294 variant in the P2RX7 gene?
rs208294 is a single nucleotide polymorphism (SNP) located in the P2RX7 (Purinergic Receptor P2X 7) gene, which is involved in ATP danger signal / NLRP3 inflammasome activation. P2RX7 encodes the P2X7 ATP receptor on macrophages and microglia, which activates the NLRP3 inflammasome upon extracellular ATP binding.
How may the rs208294 variant relate to Long COVID or ME/CFS?
P2RX7-NLRP3 inflammasome activation by extracellular ATP (released from damaged cells) drives IL-1beta secretion; variants (Arg307Gln loss-of-function) may affect inflammasome-driven inflammation in Long COVID.
Can a consumer DNA test detect the rs208294 variant?
Many consumer DNA tests such as 23andMe, AncestryDNA, and MyHeritage genotype common SNPs. ChronicDNA analyses your raw DNA file and reports on variants studied in relation to chronic illness, immune function, and metabolism. This is not a diagnostic service — results are informational and educational only.
