Apolipoprotein E Polymorphism in Schizophrenic Patients / 신경정신의학

ABSTRACT

OBJECTIVES: To explore the role of apolipoprotein E in schizophrenia, we investigated apoli-poprotein E polymorphism in groups of patients with schizophrenia and normal controls. We also examined the relationship of clinical characteristics of schizophrenia to apolipoprotein E genotypes. METHODS: Samples were obtained from 101 schizophrenic patients and 96 controls in Korea and apolipoprotein E polymorphisms were analysed using polymerase chain reaction. RESULTS: The genotype and allele frequencies did not differ from those of controls. The clinical variables of schizophrenia, such as positive and negative groups by PANSS, subtypes by DSM-IV, family history were not associated with each genotypes. CONCLUSION: We could not find the association of apolipoprotein E in Korean schizophrenic patients and it could be suggested that apolipoprotein E isoforms might not play a main role in expression of schizophrenia.
