An association study of the brain-derived neurotrophic factor Val66Met polymorphism and amphetamine response.

ABSTRACT: Although genetic factors are known to be important in addiction, no candidate genes have yet been consistently linked to drug use or abuse. Brain-derived neurotrophic factor (BDNF), which has been implicated in the behavioral response to psychomotor stimulants and potentiates neurotransmitters that are strongly linked to addiction, is a logical candidate gene to study. Using a drug challenge approach, we tested for association between BDNF G196A (val66met) genotype and subjective responses to amphetamine (AMPH). Healthy volunteers participated in a double blind, crossover design in which they received placebo, 10 mg, and 20 mg oral d-amphetamine in random order. Subjective and physical responses to ingestion of AMPH were measured at 30-min intervals after drug ingestion. Each subject was g
