    Abstract:
    VNTR polymorphisms of the serotonin transporter (hSERT) and dopamine transporter (DAT1) gene were studied in male opiate addicts. Samples of ethnic Russians and ethnic Tatars did not differ in genotype and allele frequencies. Homozygosity at hSERT (especially 10/10) was associated with early opiate addiction, while genotype 12/10 proved to be protective. In the case of DAT1, genotype 9/9 was associated with early opiate addiction. The combination of hSERT genotype 10/10 with DAT1 genotype 10/10 was shown to be a risk factor of opiate abuse under 16 years of age.
