Abstract: | The serotonergic system is implicated in the etiology of mood disorders. Among those most recently discovered serotonin receptors, the relative abundance of serotonin type 6 receptor (5-HT6) in the limbic area and the high affinity of some antidepressants to 5-HT6 receptors suggest that this receptor might be involved in the pathogenesis of mood disorders. In a population-based association study, we tested the hypothesis that the allelic variant (C267T) of the human 5-HT6 gene confers susceptibility to mood disorders. We genotyped the 5-HT6 receptor in 139 patients with mood disorders and 147 controls. The results demonstrated that there were no significant differences in genotype or allele frequencies between controls and all patients, or between controls and patients with bipolar disorders or major depression, separately.
