What is the rs4369876 variant?

rs4369876 is a SNP (single nucleotide polymorphism) in the SCN9A (Sodium Voltage-Gated Channel Alpha Subunit 9) gene. It belongs to the Pain Sensory category and is part of the Pain & Sensory Processing biological cluster. SCN9A encodes Nav1.7, a voltage-gated sodium channel critical for pain signal transmission in peripheral sensory neurons.

Biological role and pathway

This variant sits within the SCN9A gene, which is involved in the voltage-gated sodium channel signaling pathway. Genes within the Pain & Sensory Processing 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.

rs4369876 and Long COVID / ME-CFS research

SCN9A variants affecting Nav1.7 function have been studied in relation to small fiber neuropathy and chronic pain in Long COVID.
