Liver alcohol dehydrogenase in Japanese: high population frequency of atypical form and its possible role in alcohol sensitivity.
Electrophoretic and quantitative studies reveal that 85% of Japanese carry an atypical liver alcohol dehydrogenase (ADH). The frequency of ADH polymorphism is identical with the reported frequency of alcohol sensitivity in the Japanese population. This identity in population frequencies points to a causative relationship between the two phenomena and suggests that alcohol sensitivity might be due to the increased acetaldehyde formation in individuals carrying the atypical ADH gene.
