Allelic and genotypic associations of DRD2 Taq I A polymorphism with heroin dependence in Spanish subjects: a case control study

1 Jun 2007

Abstract excerpt

BACKGROUND: Conflicting associations with heroin dependence have been found involving the A1 allele of dopamine D2 receptor gene (DRD2) TaqI A polymorphism. METHODS: We compared two samples of unrelated Spanish individuals, all of European origin: 281 methadone-maintained heroin-dependent patients (207 males and 74 females) who frequently used non-opioid substances, and 145 control subjects (98 males and 47...
