In the present study we investigated the influence of a series variants in genes (the serotonin transporter, glycogen synthase kinase-3beta, inositol polyphosphatase 1-phosphate, brain-derived neurotrophic factor and activator protein 2beta) related to the action of lithium carbonate, a drug used for prophylaxis in mood disorders. We used a sample of(More)
The human serotonin transporter gene (5-HTT) is a candidate for the pathogenesis of mood disorders, including bipolar disorder (BPD). The 5-HTT gene has a 44-bp insertion/deletion polymorphism within the promoter region (5-HTTLPR) with 2 allelic forms, the long (l) and the short (s) variants, which affect transcriptional rates of the 5-HTT gene.

OBJECTIVE To investigate the influence of brain-derived neurotrophic factor (BDNF) gene variations on cognitive performance and clinical symptomatology in first-episode psychosis (FEP). METHODS We performed BDNF val66met variant genotyping, cognitive testing (verbal fluency and digit spans) and assessments of symptom severity (as assessed with the PANSS)(More)
