New Test Identifies Gene Linked to Alcohol Intolerance

A new at-home DNA test can determine if individuals have a genetic intolerance to alcohol, which is linked to a mutated gene affecting the enzyme aldehyde dehydrogenase (ALDH). This enzyme is crucial for breaking down acetaldehyde, a toxic byproduct of alcohol metabolism. Those with the gene mutation experience symptoms like facial flushing, nausea, and heart palpitations after consuming small amounts of alcohol. Experts advise such individuals to drink in moderation, stay hydrated, and maintain a balanced lifestyle. The test also checks for other sensitivities, such as gluten and lactose intolerance.
