What is the GSTA1 gene?
Alpha-class glutathione S-transferase supporting hepatic glutathione conjugation of electrophiles and oxidative-stress products.
How GSTA1 affects metabolism
When GSTA1-related function is shifted, the practical effect is interpreted through redox buffering, oxidative workload, and recovery after sleep loss, illness, alcohol, or hard training. This does not mean the pathway is active or impaired right now; it means the gene can help prioritize what to check next.
What happens when GSTA1 is altered
Altered GSTA1 signal should be treated as a DNA-based tendency, not a diagnosis. 1 claim currently passes the report-use gate. The useful question is whether symptoms, labs, and lifestyle context line up with the pathway signal.
Curated SNP evidence for GSTA1
These SNPs come from the approved study-level evidence model. Each claim is scored from curated study rows, then gated before it can influence pathway scoring.
Evidence-backed report connection
GSTA1 currently has 1 curated SNPs, 1 claim-level scores, and 1 claims eligible for pathway scoring.

GSTA1 expression and glutathione conjugation capacity tendency
rs3957357 T in the GSTA1 promoter is associated with lower GSTA1 promoter activity and lower glutathione-conjugation capacity tendency, strongest in GSTA1*B promoter-haplotype context.
GSTA1 rs3957357 T is staged as a promoter-expression marker relevant to alpha-class glutathione transferase capacity.

Common symptoms people report
- slower recovery after poor sleep or hard training
- feeling run down after alcohol, infection, or stress
- higher sensitivity to inflammation or toxic load
Biomarkers to validate
hs-CRP and GGT
Practical markers that can reflect inflammatory and oxidative load context.
ALT and AST
Adds liver stress and recovery context.
Glutathione or oxidized LDL when available
Can add more direct redox information.
Where DNA analysis helps
DNA helps decide whether GSTA1 deserves attention inside the broader Oxidative stress pathway. It is most useful when combined with biomarkers instead of used as a standalone answer.
Example interpretation
GSTA1 may add context to redox buffering, oxidative workload, and recovery after sleep loss, illness, alcohol, or hard training, especially when its SNP evidence lines up with other genes in the same pathway.
Suggested validation: hs-CRP and GGT.
What to do next
- Review the Oxidative stress pathway result before interpreting GSTA1 on its own.
- Use relevant biomarkers to confirm whether this DNA tendency is visible in current biology.
- Treat supplement or nutrition decisions as follow-up steps only after the pattern fits symptoms or labs.
