What is the rs1041983 variant?

rs1041983 is a SNP (single nucleotide polymorphism) in the NAT2 (N-Acetyltransferase 2) gene. It belongs to the Metabolism category and is part of the Pharmacogenomics biological cluster. NAT2 catalyzes N-acetylation of aromatic amines and hydrazines. Variants define slow, intermediate, and rapid acetylator phenotypes that strongly affect metabolism of isoniazid, sulfonamides, caffeine, and other drugs.

Biological role and pathway

This variant sits within the NAT2 gene, which is involved in the drug metabolism pathway. Genes within the Pharmacogenomics 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.

rs1041983 and Long COVID / ME-CFS research

NAT2 slow acetylators may have altered metabolism of some anti-infective agents. The acetylator phenotype also influences susceptibility to environmental chemical-induced oxidative stress, potentially relevant to the chemical sensitivity reported in Long COVID.

Frequently asked questions

What is the rs1041983 variant in the NAT2 gene?

rs1041983 is a single nucleotide polymorphism (SNP) located in the NAT2 (N-Acetyltransferase 2) gene, which is involved in drug metabolism. NAT2 catalyzes N-acetylation of aromatic amines and hydrazines. Variants define slow, intermediate, and rapid acetylator phenotypes that strongly affect metabolism of isoniazid, sulfonamides, caffeine, and other drugs.

How may the rs1041983 variant relate to Long COVID or ME/CFS?

NAT2 slow acetylators may have altered metabolism of some anti-infective agents. The acetylator phenotype also influences susceptibility to environmental chemical-induced oxidative stress, potentially relevant to the chemical sensitivity reported in Long COVID.

Can a consumer DNA test detect the rs1041983 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.
