What is the TPH2 gene?
Serotonin synthesis support in neural tissue.
How TPH2 affects metabolism
When TPH2-related support is weaker, serotonin signaling and turnover may be easier to destabilize under stress or poor recovery can become more relevant to validate.
What happens when TPH2 is altered
Altered TPH2 function does not guarantee a problem, but it can reduce how efficiently this system handles routine demand.
Tracked SNPs used for TPH2

The directional notes below are shared between the public gene pages and the tracked SNP report so the same SNP list drives both surfaces.

Open TPH2 in the sample report| SNP | Alias | Why it is tracked | Effect allele | Directional note | Confidence | Linked pathway |
|---|---|---|---|---|---|---|
| rs64042484 | TPH2 context signal | Tracked TPH2 variant for serotonin balance coverage expansion. | G | Tracked for completeness inside serotonin balance review. | low | Serotonin balance |
| rs64042485 | TPH2 supporting signal | Tracked TPH2 variant for serotonin balance coverage expansion. | T | Lower serotonin-balance support remains the default follow-up interpretation for TPH2. | low | Serotonin balance |
| rs64042486 | TPH2 primary signal | Tracked TPH2 variant for serotonin balance coverage expansion. | A | Lower serotonin-balance support is the main working interpretation for TPH2 in serotonin balance. | moderate | Serotonin balance |
Common symptoms people report
- serotonin balance strain showing up in everyday symptoms
- greater mismatch between habits and response
- recurrent patterns that look more stubborn than generic advice predicts
Biomarkers to validate
Sleep quality
Useful for validating TPH2 inside serotonin balance.
stress reactivity
Useful for validating TPH2 inside serotonin balance.
Where DNA analysis helps
DNA helps decide whether TPH2 belongs near the top of the pathway explanation or stays in background context.
Example Insight
TPH2 becomes more meaningful when the surrounding serotonin balance genes and biomarkers point in the same direction.
Sleep quality
What to do next
- Start with Sleep quality.
- Interpret TPH2 together with the rest of serotonin balance, not in isolation.
