23andMe CYP1A2 caffeine marker
CYP1A2 rs762551 in 23andMe raw data.
If you are searching a 23andMe raw DNA file for caffeine metabolism, the marker most people mean is rs762551. 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 rs762551 in the raw-data text file or use a local marker checker
- Treat missing rs762551 as a coverage issue, not proof that caffeine genetics do not matter
- Interpret CYP1A2 with ADORA2A, sleep, anxiety response, medications, habits, 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, how much caffeine to drink or when to stop drinking it.
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.
rs762551 is one caffeine marker
rs762551 is commonly discussed with CYP1A2 caffeine metabolism, but it is not the whole story for sleep, anxiety, blood pressure, or stimulant response.
GenoSight separates detection from interpretation
The free checker can show whether rs762551 appears in your file. A full Foods & Drinks report adds cautious habit and evidence context.
Keep caffeine genetics inside its limits.
GenoSight is educational only. Caffeine response also depends on sleep, anxiety response, blood pressure, medications, pregnancy status, smoking status, and your current caffeine habits.

Continuers762551 and 23andMe questions
Can I find CYP1A2 rs762551 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 rs762551.
What does rs762551 mean for caffeine?
rs762551 is a CYP1A2 marker commonly discussed in caffeine-metabolism research. A raw genotype is not a caffeine prescription, dosing rule, or diagnosis.
What if my 23andMe file does not show rs762551?
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 context?
Yes, if it is a compatible 23andMe raw genotype file. GenoSight can run an educational Foods & Drinks report that frames CYP1A2 with ADORA2A, caffeine habits, sleep, caveats, and source notes.
