Schizophrenia and the HLA-DRB1 Gene in the Japanese Population

Abstract

Consistent with the findings of three other Japanese studies, the findings of the present study suggest that the rate of HLA-DR1 may be higher in Japanese patients with schizophrenia than in normal Japanese subjects. No evidence for an association between schizophrenia and the rate of DR4 was obtained in this study, although the combined data from the present study and other Japanese studies support the finding of lower rates of DR4 among patients with schizophrenia.
