Night owl or early bird?
Do you function best at 7 AM or at midnight? Variants in circadian genes like CLOCK (marker rs1801260) are linked in studies to morning/evening preference. Check your own raw data file — right in the browser.
How to do it
- Don't have the file yet? Download your raw data (23andMe, MyHeritage, AncestryDNA, FTDNA).
- Look up rs1801260 in the rsID lookup to see which associations the marker has.
- Want to see your own variant? Analyze the file locally — it is not uploaded.
- Share the challenge with a friend — compare your variants!
The science, briefly
Circadian genes like CLOCK help regulate the body's day-night rhythm. Variants of rs1801260 have been linked in studies to preference for morning versus evening activity — but sleep habits, age, light exposure and work schedule play a large role. It is an association, not a verdict on your chronotype.
