What is the rs2842934 variant?

rs2842934 is a SNP (single nucleotide polymorphism) in the SULT1A1 (Sulfotransferase Family 1A Member 1) gene. It belongs to the Pharmacogenomics category and is part of the Detox & Medication Sensitivity biological cluster. SULT1A1 encodes the major phenol sulfotransferase, which sulfates phenolic drugs, neurotransmitters, and steroid hormones.

Biological role and pathway

This variant sits within the SULT1A1 gene, which is involved in the phenol sulfotransferase / drug and hormone sulfation 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.

rs2842934 and Long COVID / ME-CFS research

SULT1A1 variants (R213H copy number) affect sulfation of drugs and catecholamines; altered catecholamine sulfation may affect sympathetic tone in Long COVID dysautonomia.
