TERC Gene
Telomerase RNA Component (TERC) is a gene involved in telomere maintenance that has been studied in relation to immune function, metabolism, and chronic illness. Variants in TERC may influence how the body responds to infection, inflammation, and long-term recovery.

What is the TERC gene?
TERC encodes telomerase rna component, a protein involved in telomere maintenance. It belongs to the Genome Stability category and is part of the Oxidative Stress biological cluster. TERC encodes the RNA template component of telomerase, providing the template for telomere repeat synthesis.
Biological role and pathway
TERC is involved in the telomere maintenance pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Oxidative Stress 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 in these systems — particularly under conditions of physiological stress such as viral infection or prolonged illness.
TERC and Long COVID / ME-CFS research
TERC variants may affect telomere length maintenance; short telomeres are associated with impaired immune function and increased susceptibility to severe COVID-19 and Long COVID.

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 TERC and related genes in the oxidative stress pathway.
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 TERC gene and what does it do?
TERC (Telomerase RNA Component) is involved in telomere maintenance. TERC encodes the RNA template component of telomerase, providing the template for telomere repeat synthesis.
How may TERC gene variants relate to Long COVID or ME/CFS?
TERC variants may affect telomere length maintenance; short telomeres are associated with impaired immune function and increased susceptibility to severe COVID-19 and Long COVID.
