Method: We evaluated singlenucleotide polymorphisms of key genes within these systems in three populations of opiate abusers and controls, totaling 489 individuals from Europe and the United States with postmortem tissue.
Conclusion: Genetically influenced interactions between
glutamatergic and dopaminergic pathways in opiate abusers
Dopamine receptor D1 and postsynaptic density gene variants associate with opiate abuse and striatal expression levels. Molecular Psychiatry (2012), 1–6
