What is the NQO1 gene?
NQO1 helps reduce quinones and supports redox defense. That puts it at the overlap of detoxification and oxidative-stress buffering.
How NQO1 affects metabolism
If NQO1-related support is weaker, oxidant-heavy exposures and redox stress can become harder to buffer cleanly.
What happens when NQO1 is altered
Altered NQO1 function does not prove oxidative stress is active, but it increases the value of checking redox markers directly.
Tracked SNPs used for NQO1
Quinone handling and redox-defense support.
The directional notes below are shared between the public gene pages and the tracked SNP report so the same SNP list drives both surfaces.
| SNP | Alias | Why it is tracked | Effect allele | Directional note | Confidence | Linked pathway |
|---|---|---|---|---|---|---|
| rs1131341 | NQO1 supporting signal | Supporting NQO1 SNP for broader redox coverage. | — | No directional hint published yet. | — | Oxidative stress |
| rs1800566 | P187S | Common NQO1 variant reviewed in quinone-handling and redox-support context. | T | Often reviewed as lower quinone-defense support under oxidative load. | moderate | Oxidative stress |
Common symptoms people report
- slower recovery under high load
- feeling worse with oxidative stressors
- energy that drops faster under environmental or metabolic stress
Biomarkers to validate
GSH/GSSG ratio
Direct redox follow-up.
Oxidative stress panels
Useful for broader redox context.
Inflammation context
Adds overlap with systemic load.
Where DNA analysis helps
DNA helps decide whether quinone/redox handling deserves attention before broad antioxidant strategies are used blindly.
Example Insight
Your redox-defense pathway may be less forgiving under oxidant-heavy load than expected.
Suggested validation: GSH/GSSG ratio plus an oxidative stress panel.
What to do next
- Validate redox markers before assuming supplementation is the answer.
- Review NQO1 with GSTM1 and GCLC when recovery feels constrained.
- Use workload and symptom context with biomarkers.
