Abstract
Objectives: The glutamatergic dysfunction is one of the main hypotheses for the pathophysiology of schizophrenia. N-methyl-D-aspartate receptors are of major interest because phencyclidine, a non-competitive antagonist of N-methyl-D-aspartate receptors, produces a schizophrenia-like psychosis. Therefore, the genes encoding N-methyl-D-aspartate receptor subunits are strong candidates for schizophrenia susceptibility genes. We focused on the N-methyl-D-aspartate receptor subunit NR2D gene in the case-control study of schizophrenia. Methods: We screened for polymorphisms in exons, exon-intron boundaries and the 5′ upstream region of GRIN2D by direct sequencing in 32 Japanese patients. Out of the total 13 single-nucleotide polymorphisms identified, we genotyped 200-201 Japanese patients and 219-221 controls for nine common single-nucleotide polymorphisms (minor allele frequency over 0.05). Results: None of the nine single-nucleotide polymorphisms showed significant differences in genotype and allele frequencies between cases and controls. We observed significant associations of pairwise haplotypes in three combinations of four single-nucleotide polymorphisms, INT10SNP-EX13SNP2, EX13SNP2-EX13SNP3 and EX6SNP-EX13SNP2, with the disease even after the Bonferroni correction (P=1.094 × 10-6, Pcorrected=2.297 × 10 -5, P=2.825 × 10-6, Pcorrected=5.933 × 10-5 and P=2.02 × 10-4, P corrected=4.242 × 10-3, respectively). The same results were also obtained using the false discovery rate (BL) method at the threshold P value, 2.908 × 10-3. Conclusions: We conclude that the GRIN2D locus is a possible genomic region contributing to schizophrenia susceptibility in the Japanese population.
