ADH1B

ADH1B

A gene on chromosome 4q21-23 that encodes a member of the alcohol dehydrogenase family, which metabolise various substrates, including ethanol, retinol, other aliphatic alcohols, hydroxysteroids and lipid peroxidation products. The encoded protein plays a major role in ethanol catabolism.

Around 80 percent of Asian people (less common in Thailand and India) have a variant of the gene coding for the enzyme alcohol dehydrogenase called ADH1B, whereas almost all Japanese, Chinese, and Korean people have a variant of the gene called ADH1C, both resulting in an alcohol dehydrogenase enzyme that converts alcohol to toxic acetaldehyde at a much higher efficiency than other gene variants from Caucasians.

The rates of metabolic pathways responsible for converting alcohol to acetaldehyde and acetaldehyde to acetate are mostly influenced by functional polymorphisms on ADH1B (previously called ADH2), ADH1C (previously called ADH3),andALDH2 [5-7].
Durante los estudios de genes candidatos se han identificado los dos genes verificados de la adiccion que codifican las enzimas del metabolismo del alcohol: el alcohol deshidrogenasa ADH, gen ADH1B y el aldehido deshidrogenasa ALDH, gen ALDH2 (Befort 2001).
They looked especially at those with a key variant of a gene called ADH1B.
