What is the rs1867351 variant?

rs1867351 is a SNP (single nucleotide polymorphism) in the SLC22A1 (Solute Carrier Family 22 Member 1 (OCT1)) gene. It belongs to the Pharmacogenomics category and is part of the Detox & Medication Sensitivity biological cluster. SLC22A1 encodes organic cation transporter 1 (OCT1), expressed in the liver, which mediates hepatic uptake of metformin and other organic cations.

Biological role and pathway

This variant sits within the SLC22A1 gene, which is involved in the organic cation transport / drug metabolism pathway. Genes within the Detox & Medication Sensitivity 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.

rs1867351 and Long COVID / ME-CFS research

SLC22A1 affects drug disposition including metformin; variants may influence medication responses in Long COVID management, particularly for metabolic symptoms.
