23andMe caffeine genes
Does 23andMe test caffeine genes?
Sometimes that question means a named 23andMe report. Sometimes it means whether your raw data contains CYP1A2 or ADORA2A markers. GenoSight helps with the second path: checking a compatible raw genotype file and turning supported findings into a careful educational Foods & Drinks report.
Two questions get mixed together
Report availability and raw-marker coverage are separate.
- 23andMe report availability can change
- Raw data may include CYP1A2 or ADORA2A markers
- GenoSight checks compatible raw genotype files
- Educational only, not a caffeine dosing rule
The careful answer
Caffeine genetics gets simplified online. Start by separating a consumer report, raw data lookup, and clinical guidance into three different buckets.
If you mean a provider report
A named health or traits report is different from checking whether a downloaded raw genotype file contains caffeine-related rsIDs.
If you mean raw data
The common starting markers are CYP1A2 rs762551 for caffeine metabolism and ADORA2A rs5751876 for caffeine sensitivity context, but coverage can vary.
If you mean medical guidance
Consumer raw DNA is informational. Caffeine questions involving anxiety, insomnia, blood pressure, pregnancy, or medication interactions belong with a qualified clinician.
Source boundaries
23andMe raw-data export can help answer whether a marker appears in your file. It cannot decide your caffeine cutoff time, anxiety cause, sleep diagnosis, or medication interaction risk by itself.

Explains searching 23andMe raw data by gene, marker rsID, or genomic position and states the informational-use boundary.
23andMe raw genotype technical details
Explains strand reporting, reference genome language, marker naming, and how uncalled variants can appear in downloaded raw data.
ADORA2A caffeine sensitivity study
A commonly cited study of ADORA2A polymorphisms and caffeine-induced anxiety that should not be turned into a standalone rule.
What to do with a 23andMe raw file
Check marker coverage
Use the local caffeine checker to see whether CYP1A2 or ADORA2A markers appear without uploading the file.

Does 23andMe include caffeine genes?
It depends what you mean. 23andMe report availability can change, and raw-data marker coverage is separate. A compatible 23andMe raw genotype file may include caffeine-related markers such as CYP1A2 rs762551 or ADORA2A rs5751876, but coverage can vary by chip version and file.
Which caffeine markers should I search for in 23andMe raw data?
The two common starting points are CYP1A2 rs762551 for caffeine metabolism context and ADORA2A rs5751876 for caffeine sensitivity, arousal, anxiety, and sleep context.
Can GenoSight read my 23andMe raw data for caffeine context?
Yes, if it is a compatible 23andMe raw genotype file. GenoSight can analyze supported caffeine-related markers in an educational Foods & Drinks report with habit, sleep, and caveat context.
Can I check caffeine markers before uploading a file?
Yes. GenoSight has a browser-only caffeine raw data checker that runs locally and shows marker presence plus raw genotype strings without interpreting them.
