| Outline of Final Research Achievements |
Genome-wide association studies (GWAS) and meta-analyses have highlighted ZNF804A as a robust, genome wide supported susceptibility gene for schizophrenia; however, the biological functions of ZNF804A have not yet been fully elucidated. The aim of this study is to see the effect of ZNF804A gene on various phenotypes of brain, like neurocognition, neuroimaging, neurophysiology, personality trait and gene expressions. We also investigated the differential expression of this gene in schizophrenia. We identified a novel transcriptional variant of ZNF804A that contains an additional sequence and found that significantly fewer schizophrenic patients than controls expressed the variant in the lymphoblast. We also found that ZNF804A is involved in the TGF-β signaling. Expression levels of ZNF804A in the postmortem brain and the effect of risk genotype on expression levels were also investigated.
