▶Extended genetic effects of ADH cluster genes on the risk of alcohol dependence: from GWAS to replicationAssociationN=1,371Byung Lae Park et al.(2013)· Human Genetics
This GWAS and replication study in a Korean cohort identified genetic associations with alcohol dependence (AD), with the ADH gene cluster on chromosome 4q22-q23 and ALDH2 on 12q24 showing the strongest signals. The most significant finding was ADH1B rs1229984 (H47R) with p=2.63×10⁻²¹ and OR=2.35 in the replication cohort of 975 subjects. Conditional analyses revealed that ADH1B rs1229984 is likely the sole functional marker driving effects across the ADH cluster.
About ADH5
This gene encodes a member of the alcohol dehydrogenase family. Members of this family metabolize a wide variety of substrates, including ethanol, retinol, other aliphatic alcohols, hydroxysteroids, and lipid peroxidation products. The encoded protein forms a homodimer. It has virtually no activity for ethanol oxidation, but exhibits high activity for oxidation of long-chain primary alcohols and for oxidation of S-hydroxymethyl-glutathione, a spontaneous adduct between formaldehyde and glutathione. This enzyme is an important component of cellular metabolism for the elimination of formaldehyde, a potent irritant and sensitizing agent that causes lacrymation, rhinitis, pharyngitis, and contact dermatitis. The human genome contains several non-transcribed pseudogenes related to this gene. [provided by RefSeq, Oct 2008]
