Schizophrenia is a complex and severe psychiatric disorder manifested by a disruption in cognition and emotion along with negative (avolition, alogia, apathy, poor social functioning) and positive (hallucinations, delusions) symptoms [1, 2]. According to the neurodevelopmental theory, the etiology of schizophrenia may involve pathological processes in the brain induced by environmental factors during the early stage of brain formation [reviewed in [3]]. These processes result in genetic abnormalities leading to dysfunction of specific neural network, which might contribute to the premorbid signs for the later developed schizophrenia [3]. Evidence from epidemiological and genetic studies suggest a high degree of heritability of schizophrenia and point to a number of potential candidate genes that may be perturbed early in development leading ultimately to the development of psychotic symptoms [reviewed in [3–5]]. However, the molecular etiopathomechanisms of this disorder are still unclear.
