OGG1 Gene

What is the OGG1 gene?

OGG1 encodes 8-oxoguanine dna glycosylase, a protein involved in base excision repair of oxidative DNA damage. It belongs to the Genome Stability category and is part of the Oxidative Stress biological cluster. OGG1 encodes the primary repair enzyme for 8-oxoguanine, the most common oxidative DNA lesion generated by reactive oxygen species.

Biological role and pathway

OGG1 is involved in the base excision repair of oxidative DNA damage 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.

Known genetic variants

The following variants (SNPs) in the OGG1 gene have been studied in relation to genome stability and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.

Conditions studied in relation to OGG1

Research into OGG1 variants has explored associations with the following conditions. These are areas of scientific investigation and do not imply that OGG1 causes or treats any condition.

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 OGG1 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.
