Half of the differentially expressed genes validated by at least two microarray studies in schizophrenia were also significantly altered in this study.

1Gene symbol: the previously compiled post-mortem microarray data since 2000, which listed prominent and concordant gene expression differences replicated in multiple studies of schizophrenia across various cortical regions [34], [35]. 2Detection indicated whether the gene was present in the DEGs we detected in this study. Around half of the differentially expressed genes in schizophrenia confirmed previously in two or more microarray studies were also observed here by sequencing.
