Estimation of VNTR-polymorphism in the gene of dopamine transporter in menof different nationalities with acute alcoholic psychosis

VNTR-polymorphism of the gene of dopamine transporter (DAT) in men of the R ussian and Tatar nationalities with acute alcoholic psychoses was analyzed by method of the polymerase chain reaction. There were no differences in th e distribution of frequencies of genotypes and alleles of DAT gene between the populations examined. There was association between an allele variant w ith 9 units of DAT gene repetition (in homozygous state first of all), and early development of alcoholic dependence and acute alcoholic psychosis.
