Association study of the serotonin transporter promoter polymorphism and symptomatology and antidepressant response in major depressive disorders.
The serotonin transporter (5-HTT) is the site of primary action for the selective serotonin reuptake inhibitors (SSRIs). Previous Western reports have demonstrated that the lallele of the 5-HTT gene-linked polymorphic-region (5-HTTLPR) polymorphism is associated with better SSRI antidepressive effects than the s allele, however, another study of a Korean population has produced a contrasting finding. The present study tested the hypothesis that the 5-HTTLPR genetic polymorphism is associated with SSRI antidepressant response by evaluating total and cluster depressive symptoms for 121 Chinese patients diagnosed with major depression. Analysis of the results reveals that patients with the l/l genotype had a significantly better response to SSRI (fluoxetine) when compared with s allele carriers, as evaluated on the basis of total (P = 0.013), core (P = 0.011), and psychic-anxiety (P = 0.005) and somatic-anxiety (P = 0.002) Hamilton Depression Rating Scale-score percentage change. Our findings confirm reports that the l allele is associated with better SSRI response.
