Abstract

Objective: This study investigated whether the brain-derived neurotrophic factor (BDNF) gene Val66Met single-nucleotide polymorphism (SNP) is associated with antipsychotic-induced tardive dyskinesia (TD) in schizophrenia. Methods: Genotyping was performed for the BDNF gene Val66Met SNP in Korean schizophrenic patients with (n = 83) and without TD (n = 126) who were matched for antipsychotic drug exposure and other relevant variables. Results: The frequencies of genotypes (χ2 = 2.37, p = 0.306) and alleles (χ2 = 0.03, p = 0.867) did not differ significantly between these two groups. Conclusion: These findings suggest that the BDNF polymorphism does not play a major role in the susceptibility to TD in schizophrenic patients. Crown
