Single nucleotide polymorphisms (SNPs) in ADH1B and ALDH2, which encode alcohol dehydrogenase 1B and aldehyde dehydrogenase 2, respectively, are responsible for ethanol-metabolizing activity and alcohol-related disease. We developed a simple and rapid polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP) method for the simultaneous genotyping of the genes in a single-tube reaction. Using an alkaline lysate of a human hair root as a template, SNP-containing regions of each gene were PCR-amplified simultaneously. The PCR products were directly applied to double restriction digestion, followed by agarose gel band analysis. The duplex PCR-RFLP allows for the simultaneous and accurate determination of the SNP genotypes of ADH1B and ALDH2 within 1.2 h.
