抜粋

The glutamatergic dysfunction hypothesis of schizophrenia suggests genes involved in glutamatergic transmission as candidates for schizophrenia-susceptibility genes. The GluR6 kainate receptor gene GRIK2 is located on chromosome 6q16.3-q21, a schizophrenia susceptibility region, as suggested by multiple linkage studies. We examined 15 SNPs evenly distributed in the entire GRIK2 region (>700 kb) in Japanese patients with schizophrenia (n=100) and controls (n=100). Neither genotype nor allele frequency showed a significant association with the disorder. We constructed 2-SNP haplotypes from the 15 SNPs. Although we observed three long linkage disequilibrium blocks (>150 kb) within the GRIK2 region, none of the pairwise haplotypes showed a significant association with the disorder. Therefore, we conclude that GRIK2 does not play a major role in the pathogenesis of schizophrenia in the Japanese population.
