What is the MTNR1A gene?
Melatonin signaling and circadian timing.
How MTNR1A affects metabolism
When MTNR1A-related support is weaker, sleep timing and circadian recovery may be easier to disrupt can become more relevant to validate.
What happens when MTNR1A is altered
Altered MTNR1A function does not guarantee a problem, but it can reduce how efficiently this system handles routine demand.

Open MTNR1A in the sample report| SNP | Alias | Why it is tracked | Effect allele | Directional note | Confidence | Linked pathway |
|---|---|---|---|---|---|---|
| rs53633663 | MTNR1A primary signal | Tracked MTNR1A variant for sleep / circadian regulation coverage expansion. | T | Less stable sleep and circadian regulation is the main working interpretation for MTNR1A in sleep / circadian regulation. | moderate | Sleep / circadian regulation |
| rs53633664 | MTNR1A supporting signal | Tracked MTNR1A variant for sleep / circadian regulation coverage expansion. | A | Less stable sleep and circadian regulation remains the default follow-up interpretation for MTNR1A. | low | Sleep / circadian regulation |
| rs53633665 | MTNR1A context signal | Tracked MTNR1A variant for sleep / circadian regulation coverage expansion. | C | Tracked for completeness inside sleep / circadian regulation review. | low | 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 MTNR1A inside sleep / circadian regulation.
sleep regularity
Useful for validating MTNR1A inside sleep / circadian regulation.
Where DNA analysis helps
DNA helps decide whether MTNR1A belongs near the top of the pathway explanation or stays in background context.
Example Insight
MTNR1A 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 MTNR1A together with the rest of sleep / circadian regulation, not in isolation.
