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.
