GSK-3? and BDNF genes may not be associated with venlafaxine treatment response in Chinese of Han ethnicity.

ABSTRACT: Purpose:Venlafaxine is one of the commonly prescribed antidepressants for major depressive disorder (MDD). Accumulated evidence revealed the involvement of glutamatergic system in the pathophysiology of MDD and antidepressant treatment. Methods:We recruited 193 MDD patients who have been taking venlafaxine for 6 weeks, and investigated whether single nucleotide polymorphisms (SNPs) in GSK-3? and BDNF were associated with treatment response. Nine SNPs were selected randomly depending on association studies. Efficacy of treatment was determined by 17-item Hamilton Rating Scale. Allele and genotype frequencies were compared between responders and nonresponders. Results:After adjusting the false discovery rate, no significant difference was observed between response and nonresponse groups in allele or genotype distributions after venlafaxine treatment for 6 weeks. Conclusion:Our results indicated that genetic variants in the GSK-3? and BDNF may not be associated with treatment response in MDD patients treated with venlafaxine.
