Abstract | OBJECTIVE: METHODS: Genotyping of BDNF Val66Met polymorphism was carried out for 135 schizophrenic patients and 483 healthy controls with TaqMan probe technology. The patients' psychotic symptoms were assessed using the positive and negative syndrome scale (PANSS). RESULTS: A significant difference was found in genotype distribution and allelic frequency of the Val66Met polymorphism between the two groups (P< 0.01). In patients, Met homozygotes had a significantly higher score in anxiety/depression factor, cognitive factor and total score of PANSS than Val carriers. CONCLUSION:
BDNF gene Val66Met polymorphism is associated with the pathogenesis of schizophrenia. The Met/Met genotype of BDNF Val66Met variant may be a risk factor for symptoms in first episode schizophrenia patients.
