MyHeritage CYP1A2 caffeine marker
CYP1A2 rs762551 in MyHeritage raw data.
If you are searching a MyHeritage raw DNA data 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 MyHeritage raw DNA data file, not a PDF or screenshot
- Search for rs762551 in the raw-data text file or use a local marker checker
- Treat a missing result as a coverage or no-call issue, not a clinical answer
- 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.
MyHeritage exports raw DNA data
MyHeritage support describes a raw DNA data file that can be downloaded and interpreted by third-party services, with its own format and caveats.
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 MyHeritage questions
Can I find CYP1A2 rs762551 in MyHeritage raw DNA data?
Sometimes. MyHeritage 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 MyHeritage 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 MyHeritage file for caffeine context?
Yes, if it is a compatible MyHeritage raw genotype file. GenoSight can run an educational Foods & Drinks report that frames CYP1A2 with ADORA2A, caffeine habits, sleep, caveats, and source notes.
