What is the PER3 gene?
Sleep timing and circadian preference support.
How PER3 affects metabolism
When PER3-related support is weaker, sleep timing and circadian recovery may be easier to disrupt can become more relevant to validate.
What happens when PER3 is altered
Altered PER3 function does not guarantee a problem, but it can reduce how efficiently this system handles routine demand.
Tracked SNPs used for PER3
Sleep timing and circadian preference support.
The directional notes below are shared between the public gene pages and the tracked SNP report so the same SNP list drives both surfaces.

| rs28418949 | PER3 supporting signal | Tracked PER3 variant for sleep / circadian regulation coverage expansion. | C | Less stable sleep and circadian regulation remains the default follow-up interpretation for PER3. | low | Sleep / circadian regulation |
| rs28418950 | PER3 primary signal | Tracked PER3 variant for sleep / circadian regulation coverage expansion. | A | Less stable sleep and circadian regulation is the main working interpretation for PER3 in sleep / circadian regulation. | moderate | Sleep / circadian regulation |
Common symptoms people report
- sleep / circadian regulation 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
melatonin timing
Useful for validating PER3 inside sleep / circadian regulation.
sleep regularity
Useful for validating PER3 inside sleep / circadian regulation.
Where DNA analysis helps
DNA helps decide whether PER3 belongs near the top of the pathway explanation or stays in background context.
Example Insight
PER3 becomes more meaningful when the surrounding sleep / circadian regulation genes and biomarkers point in the same direction.
melatonin timing
What to do next
- Start with melatonin timing.
- Interpret PER3 together with the rest of sleep / circadian regulation, not in isolation.
