Polymorphism Description: G to A substitution at base 1510 in exon 12 which causes an amino acid Glu to Lys change. The Lys allele is the dominant negative variant that is strongly associated with resistance to alcoholism and the flushing reaction to ethanol found in some individuals of East Asian ancestry. This polymorphism is located at codon 487 in the mature peptide. In the initial product of translation, which includes a signal peptide (17 aa), the polymorphism is located at codon 504. In traditional usage the Glu allele is number 1 (eg: ALDH2*1) and the Lys allele is number 2 (eg: ALDH2*2).
