Luczak and colleagues’ (2006) meta-analysis suggested that Asian individuals who are the most protected from alcohol abuse possess one or two copies of the ADH1B*2 allele. Specifically, Asians with two ADH1B*2 alleles were five times less likely to be dependent on alcohol than were those who did not possess this allele (Luczak et al. 2006). The gene discussed is ADH1B; the disease is alcohol abuse.
