Research Abstract

We have performed high resolution genome wide copy number (CNV) screening of Japanese schizophrenic patients. Besides the known large CNVs that are previously reported to be associated with schizophrenia, we found novel variations. Smaller CNVs were followed up using lymphoblastoid cell lines (LCL) in order to measure expressional impact. No association between VIPR2duplication and schizophrenia was identified. In conclusion, our study demonstrated that combination of high resolution CNV screening and transcriptomics is useful methodfor investigating genetic susceptibility to schizophrenia.
