23andMe ADORA2A caffeine marker
ADORA2A rs5751876 in 23andMe raw data.
If you are searching a 23andMe raw DNA file for caffeine sensitivity, the marker most people mean is rs5751876. GenoSight can help you check whether that marker is present, then keep interpretation cautious inside a broader educational Foods & Drinks report.
Start with marker coverage
Do this before interpreting the raw letters.
- Use the downloaded 23andMe raw genotype file, usually a zipped text file
- Search for rs5751876 in the raw-data text file or use a local marker checker
- Treat missing rs5751876 as a coverage issue, not proof that caffeine sensitivity does or does not apply
- Interpret ADORA2A with CYP1A2, caffeine dose, timing, sleep, stress, medications, and clinician guidance
What to know before you search the file.
A raw-data search can answer a narrow coverage question. It cannot tell you, by itself, whether caffeine causes anxiety or sleep disruption for you.
23andMe raw data is informational
23andMe says raw data has undergone general quality review, but only a subset of markers are individually validated and the data is not for medical or diagnostic use.
rs5751876 is one sensitivity marker
rs5751876 is commonly discussed with ADORA2A caffeine sensitivity, but it is not the whole story for anxiety, arousal, sleep, or tolerance.
GenoSight separates detection from interpretation
The free checker can show whether rs5751876 appears in your file. A full Foods & Drinks report adds cautious habit and evidence context.
Keep caffeine sensitivity genetics inside its limits.
GenoSight is educational only. Caffeine response also depends on dose, timing, sleep debt, stress, medications, baseline anxiety, tolerance, and clinician guidance where relevant.

Continuers5751876 and 23andMe questions
Can I find ADORA2A rs5751876 in 23andMe raw DNA data?
Sometimes. 23andMe raw-data export, chip version, and no-call results can vary, so the right first step is checking whether your specific downloaded file contains rs5751876.
What does rs5751876 mean for caffeine sensitivity?
rs5751876 is an ADORA2A marker often discussed around caffeine-related arousal, anxiety, and sleep response. A raw genotype is not an anxiety diagnosis, insomnia diagnosis, or caffeine cutoff rule.
What if my 23andMe file does not show rs5751876?
That usually means the marker is missing, uncalled, or represented differently in that file. It does not prove anything clinically by itself.
Can GenoSight analyze my 23andMe file for caffeine sensitivity context?
Yes, if it is a compatible 23andMe raw genotype file. GenoSight can run an educational Foods & Drinks report that frames ADORA2A with CYP1A2, caffeine timing, sleep, caveats, and source notes.
