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:

Genotype	What it's associated with
GG	Typical alcohol metabolism — no ALDH2 flush variant.
AG	One ALDH2 flush variant — you may flush and break down alcohol's acetaldehyde more slowly.
AA	Two 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.
