Alcohol flush

rs671 · gene ALDH2 · category Metabolism · Free in the Quanome app

Your DNA file reports your genotype at rs671 — a marker in the ALDH2 gene that studies link to alcohol flush. Here's what each genotype is associated with:

GenotypeWhat it's associated with
GGTypical alcohol metabolism — no ALDH2 flush variant.
AGOne ALDH2 flush variant — you may flush and break down alcohol's acetaldehyde more slowly.
AATwo ALDH2 flush variants — strong flush response; alcohol is poorly tolerated.

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.
