| Popis: | The Disrupted-in-Schizophrenia 1 (DISC1) gene plays a role in the regulation of neural development. Previous evidence from genetic association and biological studies implicates the DISC1 gene as having a role in the pathophysiology of schizophrenia. In the present study, we explored the association between DISC1 missense mutation rs821616 (Ser704Cys) single nucleotide polymorphism (SNP) and four other SNPs (rs1772702, rs1754603, rs821621, rs821624) in the related haplotype block and schizophrenia in the Japanese population. We could not find a significant association of selected SNPs with schizophrenia after correction for multiple testing. We performed a meta-analysis of the Ser704Cys variant in schizophrenia using data from the present study and five previous Japanese population studies, and found no association with schizophrenia. We also examined DISC1 immunoreactivity in postmortem prefrontal cortex specimens of schizophrenia patients compared to control samples. The immunoreactivity revealed a significant decrease of DISC1 protein expression in the schizophrenia samples after ruling out potential confounding factors. However, the Ser704Cys variant did not show effects on DISC1 immunoreactivity. These results provide evidence that this functional genetic variation of DISC1 do not underlie the pathophysiology of schizophrenia in the Japanese population. |
