Interaction between 5-HT1A and BDNF genotypes increases the risk of treatment-resistant depression.
Several studies have linked 5-HT1A C1019G and BDNF G196A (Val66Met) gene polymorphisms to major depressive disorder (MDD) and the actions of antidepressants. We attempt to show that the interaction between 5-HT1A and BDNF polymorphism predicts the risk of treatment-resistant depression. The sample consists of 119 patients with treatment-resistant MDD and 392 controls. 5-HT1A C1019G and BDNF G196A (Val66Met) polymorphisms were studied. The combination of 5-HT1A GG and BDNF GA + AA genotypes is associated with an increased risk of depression.
