Your DNA file reports your genotype at rs762551 — a marker in the CYP1A2 gene that studies link to caffeine metabolism. Here's what each genotype is associated with:

Genotype	What it's associated with
AA	Fast caffeine metabolizer — you clear caffeine relatively quickly.
AC	Intermediate-to-slow caffeine metabolizer.
CC	Slow caffeine metabolizer — caffeine lingers; afternoon coffee may affect your sleep.

Educational only — not medical or diagnostic advice. A single marker is one of many factors; strand orientation varies between files. Always consult a qualified clinician about your health.
