ADH1B kodiert für die Alkoholdehydrogenase 1B, ein Enzym, das Ethanol zu Acetaldehyd abbaut. Bestimmte Varianten (z. B. rs1229984) beschleunigen diesen Schritt, was bei Alkoholkonsum zu einer schnellen Anhäufung von Acetaldehyd führt – einem toxischen Zwischenprodukt. Die typischen Symptome wie Gesichtsrötung, Übelkeit, Herzrasen oder Kopfschmerzen sind eine Alkoholintoleranz, keine echte Allergie. Eine Allergie ist eine immunologische Reaktion (IgE-vermittelt) gegen ein Allergen, während die ADH1B-bedingte Reaktion auf der Toxizität von Acetaldehyd beruht. Echte Alkoholallergien sind extrem selten und werden meist durch andere Inhaltsstoffe (z. B. Sulfite, Histamin, Getreideproteine) ausgelöst. Ein DTC-DNA-Test, der ADH1B-Varianten zeigt, gibt daher keine Auskunft über ein Allergierisiko, sondern allenfalls über die genetische Neigung zu Alkoholintoleranz. Diese Information ist zudem stark von der Abstammung abhängig: Die schützende Variante (langsamer Abbau) ist in ostasiatischen Populationen häufig, in europäischen selten. Die klinische Relevanz liegt nicht in der Allergiediagnostik, sondern in der Assoziation mit Alkoholkonsumverhalten und bestimmten Krebsrisiken (z. B. oberer Aerodigestivtrakt), insbesondere bei gleichzeitigem ALDH2-Mangel. Für Allergiefragen ist der Test nicht geeignet; hier sind Anamnese, Hauttests und spezifische IgE-Bestimmungen die Mittel der Wahl. Verbraucher sollten sich nicht von Marketingversprechen täuschen lassen, die ADH1B als „Allergiegen“ darstellen.","area":"gesundheit","canonical_id":"gesundheit:canonical-97f905aff972ddc6f5d18c32","id":"public-d8740267e1fd0f4cf44f2b75","kind":"qa","language":"de","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Myths vs Facts: ADH1B und allergy","score":31.24601688,"snippet":"Der Mythos, dass ein ADH1B-Gentest eine Allergie vorhersagen oder erklären kann, ist irreführend.
