[Polymorphism of the serotonin receptor (5-HTR2A) gene and verbal fluency in normalcy and schizophrenia].

To study the effect of the serotonergic brain system on verbal fluency (i.e., the ability to rapidly extract necessary words from the vocabulary), the T102C polymorphism of the serotonin receptor type 2A (5-HTR2A) gene was tested for association with verbal fluency in 108 patients with schizophrenia or schizotypic disorders and 97 mentally healthy individuals. A significant association was observed only in male schizophrenics (N = 67), with homozygotes A2A2 having lower verbal fluency. The results did not support the association between the 5-HTR2A polymorphism and verbal fluency in normalcy, and agree with the assumed contribution of genotype A2A2 to the severity of schizophrenia.
