| Association of the gastric alcohol dehydrogenase gene ADH7 with variation in alcohol metabolism. |

| ABSTRACT |
|
|
|
| Seven alcohol-metabolizing enzymes are encoded by the human alcohol dehydrogenase (ADH) gene cluster on chromosome 4q22-23. One of these genes, ADH7, is uniquely expressed in the stomach mucosa and can influence metabolism of alcohol before its absorption into the blood. However, the contribution of ADH7 to the overall genetic variation in alcohol oxidation in vivo is unknown. Data on in vivo alcohol metabolism were obtained for 206 Australian twin pairs of Caucasian ancestry, following ingestion of a standard dose (0.75 g kg(-1) body weight) of alcohol. Twenty-five single nucleotide polymorphisms that cover the ADH7 encoding region were genotyped. The patterns of linkage disequilibrium among these SNPs identified a recombinational hotspot within intron 7 of the ADH7 gene. A model for the absorption and elimination of alcohol from the body led to the identification of haplotypes associated with inter-individual variation in the early stages of alcohol metabolism. These are within a 35 kb DNA tract contained in the region 5' of intron 7 in the ADH7 gene. The region accounts for 18% of the linkage for alcohol concentration associated with the ADH region, or approximately 11% of the genetic variance. |
