NQO1 Gene Overview
What It Does:
The NQO1 gene encodes an enzyme involved in the Phase II detoxification pathway, converting reactive and toxic molecules into less harmful compounds. It also helps recycle antioxidants like Vitamin E and Coenzyme Q10, which protect cells from free radical damage.
Why This Matters:
NQO1 supports the body’s defenses against oxidative stress and contributes to DNA stability, energy production, and overall cellular health.
Understanding the NQO1 Variant
Key Mutation:
- Pro187Ser C>T
Impact Allele:
- T Allele (Negative)
What It Means for You:
- Enzyme Activity:
- TT genotype: Complete loss of enzyme activity.
- CT genotype: Intermediate enzyme activity.
- Detoxification:
- Reduced ability to detoxify estrogen metabolites, leading to an increase in harmful compounds that may cause DNA damage.
- Antioxidant Support:
- Impaired recycling of antioxidants like Vitamin E and Coenzyme Q10, reducing their ability to neutralize free radicals.
- Health Risks:
- Associated with increased cancer risk in the general population due to poor detoxification and oxidative stress.
Next Steps:
- Contact Your Genomics Specialist or Doctor: Discuss how this variant impacts your detoxification capacity and health risks.
- Support Antioxidant Defense:
- Increase intake of antioxidant-rich foods (e.g., berries, nuts, leafy greens).
- Consider Vitamin E and Coenzyme Q10 supplements under medical supervision.
- Focus on Detox-Friendly Habits:
- Avoid exposure to environmental toxins like tobacco smoke and grilled meats.
- Hydrate adequately to support natural detox pathways.
