ADH7

ADH7

A gene on chromosome 4q23-q24 that encodes class-IV alcohol dehydrogenase 7 mu or sigma subunit, which like other alcohol dehydrogenases metabolises various substrates, including ethanol, retinol, other aliphatic alcohols, hydroxysteroids and lipid peroxidation products. ADH7 is inefficient in ethanol oxidation; it is the most active as a retinol dehydrogenase and may participate in synthesising retinoic acid—which is required for cellular differentiation. ADH7 is highly expressed in the stomach.

ADH7 variation modulates extraversion and conscientiousness in substance-dependent subjects.
More recent evidence suggests that genetic variants in the ADHIA, ADHIB, ADHI C ADHS, ADH6, and ADH7 genes are associated with illicit drug dependence and that this association is not purely attributable to co-morbid alcohol dependence (Luo et al.
Finally, variations in the ADH7 gene may play a protective role against alcoholism through epistatic effects.
The subunits are encoded by six different genetic loci (ADH1A, ADH1B*1, ADH1C*1, and ADH4-ADH7--formerly ADH1 through ADH7, respectively).

An association study by Osier and colleagues (2004) found a potential epistatic interaction between the ADHIB and ADH7 genes among a Han Chinese population.
ADH1, ADH2, ADH3, ADH4, ADH6, ADH5, ADH7 and ADH8 primers, Saccharomyces sppstrains used on wine production identifying variations at DNA level among the yeasts (Raton, 2004).
For example, several studies found other variations in and near the ADH1B gene, as well as in or near the ADH4, ADH1C, ADH5, ADH6, and ADH7 genes that affect risk for alcoholism or the level of alcohol consumption (see the article by Hurley and Edenberg, pp.
ADH7 encodes [sigma]-ADH, which contributes to both ethanol and retinol oxidation.
The ADH7 gene has a limited expression pattern and mainly is found in endothelial cells, such as those lining the esophageal and stomach tissues, as well as during embryonic development when it may contribute to the metabolism of retinol, a form of vitamin A (Hurley et al.
