What is the rs1800629 variant?

rs1800629 is a SNP (single nucleotide polymorphism) in the TNF (Tumor Necrosis Factor) gene. It belongs to the Immune Signaling category and is part of the Immune System & Inflammation biological cluster. TNF encodes tumor necrosis factor, a central mediator of systemic inflammation, apoptosis, and immune cell activation.

Biological role and pathway

This variant sits within the TNF gene, which is involved in the cytokine signaling pathway. Genes within the Immune System & Inflammation 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.

Genetic insights from DNA data

Consumer DNA files from 23andMe, AncestryDNA, and MyHeritage contain raw SNP data. When you upload your file to ChronicDNA, the analysis engine checks your genotype against a curated panel of 80+ genes selected for their relevance to Long COVID, ME/CFS, and connected biological pathways - some of which may include TNF and the rs1800629 variant.

The report is educational - it explains which variants you carry, what the research says about them, and how they fit into the biological pathways most relevant to chronic illness. Results are presented in plain English with appropriate scientific context, no medical jargon, no scare tactics. All results should be discussed with a qualified healthcare provider.

Frequently asked questions

What is the rs1800629 variant in the TNF gene?

rs1800629 is a single nucleotide polymorphism (SNP) located in the TNF (Tumor Necrosis Factor) gene, which is involved in cytokine signaling. TNF encodes tumor necrosis factor, a central mediator of systemic inflammation, apoptosis, and immune cell activation.

How may the rs1800629 variant relate to Long COVID or ME/CFS?

TNF variants may influence the magnitude of inflammatory responses and tissue damage associated with Long COVID.

Can a consumer DNA test detect the rs1800629 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.
