A-1438-G serotonin receptor type 2A (5-HTR2A) gene polymorphism in patients with schizophrenia

A-1438-G 5-HTR2A gene polymorphism is known to be related to some clinical presentations of endogenous psychoses, in particular, of schizophrenia. The present study aim was to study association between clinical appearances of schizophrenia and A-1438-G allelic polymorphism. Alleles (A and G) and genotypes (AA, AG and GG) distribution did not significantly differ between patients and control groups. No association has been found between the genotypes and clinical characteristics of the patients, such as age at disease onset, age at psychosis manifestation, as well as positive, negative and general psychopathological symptoms severity measured by PANSS.
