What is the UGT1A4 gene?
Phase-II UGT enzyme contributing to substrate-specific glucuronidation capacity.
How UGT1A4 affects metabolism
When UGT1A4-related function is shifted, the practical effect is interpreted through estrogen-like hormone clearance, steroid bioavailability, and liver phase-I or phase-Ii context. 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 UGT1A4 is altered
Altered UGT1A4 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 UGT1A4
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
UGT1A4 currently has 1 curated SNPs, 1 claim-level scores, and 1 claims eligible for pathway scoring.

UGT1A4 glucuronidation activity
rs2011425 G is associated with higher UGT1A4 glucuronidation activity for the checked substrate context.
UGT1A4 rs2011425 is staged as a phase-II glucuronidation claim, with pathway placement treated as close proxy rather than estrogen-specific evidence.
Common symptoms people report
- hormone-context questions that need lab confirmation
- symptoms that vary with body composition, alcohol, medication, or liver context
- unexpected SHBG, estradiol, or testosterone patterns
Biomarkers to validate
Estradiol, testosterone, and SHBG
Checks whether hormone balance is actually relevant.
ALT, AST, and GGT
Adds liver clearance context.
Medication and alcohol context
Helps separate genetics from stronger external drivers.
Where DNA analysis helps
DNA helps decide whether UGT1A4 deserves attention inside the broader Estrogen metabolism pathway. It is most useful when combined with biomarkers instead of used as a standalone answer.
Example interpretation
UGT1A4 may add context to estrogen-like hormone clearance, steroid bioavailability, and liver phase-I or phase-Ii context, especially when its SNP evidence lines up with other genes in the same pathway.
Suggested validation: Estradiol, testosterone, and SHBG.
What to do next
- Review the Estrogen metabolism pathway result before interpreting UGT1A4 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.
