摘要: People with a genetic predisposition for substance abuse have defects in genes the opioid peptides and receptors. A high number of polymorphisms been detected mu-opioid receptor, some which result pharmacological alterations. The peptide proopiomelanocortin proved extraordinarily rich mutations that often lead to severe phenotypical consequences. Prodynorphin displays polymorphic regulation transcription. Variants mu- delta-opioid receptor showed positive associations opiate and/or alcohol addiction studies. However, these were weak, indicating small contribution system disorders.
