No Association Between AKT1 Polymorphisms and Methamphetamine Addiction in Iranian Population.

Previous studies have shown a high level of heritability for most kinds of substance abuse. Certain single nucleotide polymorphisms (SNPs) or haplotypes have been shown to influence methamphetamine abuse or the related psychosis. Among the most related pathways in dependence to methamphetamine are dopaminergic system-related genes especially V-akt murine thymoma viral oncogene homolog 1 (AKT1). In the current investigation, we genotyped two intronic variants within the AKT1 gene (rs2494743 and rs2498794) in a population of Iranian methamphetamine-dependent individuals and controls. There were no significant differences in alleles, genotypes, or haplotype frequencies of rs2494743 and rs2498794 between cases and controls. Consequently, our study excludes participation of these SNPs in susceptibility to methamphetamine dependence. However, other variants within this gene might affect this trait, so future studies are needed to assess associations between other AKT1 variants and methamphetamine dependence.
