What is the CAT gene?
CAT encodes catalase, one of the enzymes that helps clear hydrogen peroxide. That makes it a direct peroxide-buffering gene inside oxidative-stress defense.
How CAT affects metabolism
If catalase-related buffering is weaker, oxidative load can accumulate more easily when other redox systems are already under demand.
What happens when CAT is altered
Altered CAT function does not prove active oxidative stress, but it increases the value of direct redox validation.
Tracked SNPs used for CAT
Catalase buffering of hydrogen peroxide.
| SNP | Alias | Why it is tracked | Linked pathway |
|---|---|---|---|
| rs1001179 | CAT promoter signal | Common catalase SNP reviewed in peroxide-buffering context. | Oxidative stress |
| rs769217 | CAT supporting signal | Supporting catalase SNP for broader antioxidant coverage. | Oxidative stress |
Common symptoms people report
- slower recovery
- greater sensitivity under high oxidative load
- fatigue that feels recovery-limited
Biomarkers to validate
GSH/GSSG ratio
Useful redox context.
Oxidative stress panels
Adds broader oxidant-load context.
Inflammation context
Helpful when systemic load overlaps.
Where DNA analysis helps
DNA helps show when peroxide buffering deserves attention inside a broader redox review.
Example Insight
Your peroxide-buffering capacity may deserve closer follow-up under sustained oxidative load.
Suggested validation: GSH/GSSG ratio plus an oxidative stress panel.
What to do next
- Validate redox markers before assuming low catalase support is active.
- Review CAT with GPX1 and SOD2 rather than alone.
- Use recovery and workload context in interpretation.
