Objectives: Glutamatergic dysfunction is one of the major hypotheses of schizophrenia pathophysiology. We have been conducting systematic studies on the association between glutamate receptors and schizophrenia. We focused on the metabotropic glutamate receptor type 3 gene (GRM3) as a candidate for schizophrenia susceptibility. Methods: We genotyped Japanese schizophrenics (n = 100) and controls (n= 100) for six single nucleotide polymorphisms (SNPs) located in the GRM3 region at intervals of approximately 50 kb. Statistical differences in genotype, allele and haplotype frequencies between cases and controls were evaluated by the χ2 test and Fisher's exact probability test at a significance level of 0.05. Haplotype frequencies were estimated by the EM algorithm. Results: A case-control association study identified a significant difference in allele frequency distribution of a SNP, rs1468412, between schizophrenics and controls (P=0.011). We also observed significant differences in haplotype frequencies estimated from SNP frequencies between schizophrenics and controls. The haplotype constructed from three SNPs, including rs1468412, showed a significant association with schizophrenia ( P= 8.30 × 10-4). Conclusions: Our data indicate that at least one susceptibility locus for schizophrenia is situated within or very close to the GRM3 region in the Japanese patients.
