rs25644

What is the rs25644 variant?

rs25644 is a SNP (single nucleotide polymorphism) in the P2RX4 (Purinergic Receptor P2X 4) gene. It belongs to the Neurological category and is part of the Neurological & Cognitive Function biological cluster. P2RX4 encodes a purinergic receptor on microglia and sensory neurons that mediates pain signaling and microglial activation.

Biological role and pathway

This variant sits within the P2RX4 gene, which is involved in the microglial purinergic signaling / nociception pathway. Genes within the Neurological & Cognitive Function 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.
