Abstract

Though initial report from Japan showed positive association of schizophrenia with dinucleotide repeat polymorphism in the NT-3 gene, subsequent studies showed mixed results. Therefore we conducted a replication study with Korean schizophrenics and matched controls who share similar ethnic background with Japanese population. The frequency of allele of dinucleotide repeat at 147 base pairs in the NT-3 gene was slightly increased, however, failed to reach statistical significance(${\chi}^2$=1.884, df=1, p<0.170) between the two groups. These findings do not support an association of NT-3 gene polymorphism with schizophrenia in Korean sample.
