We investigated the convergence of putative schizophrenia risk genes in brain co-expression networks in postmortem human prefrontal cortex (DLPFC), hippocampus, caudate nucleus and dentate gyrus granule cells, parsed by specific age periods (total N=833). The results support an early prefrontal involvement in the biology underlying schizophrenia, while also revealing a dynamic interplay of regions in which age-parsing explains more variance in schizophrenia risk compared to lumping all age periods together. Across multiple data sources and publications, we identify 28 genes that are the most consistently found partners in modules enriched for putative schizophrenia risk genes in DLPFC; 23 are novel associations with schizophrenia. In iPSC-derived neurons, the unique relationship of these genes with putative schizophrenia risk genes is maintained. The genetic architecture of schizophrenia is embedded in shifting co-expression patterns across brain regions and across time, potentially underwriting its shifting clinical presentation.</em> <strong>Data Files:<br> DLPFC hit.genes_kb_200__online.version.zip: </strong><br> Interactive Sankey plot for age-parsed DLPFC networks with SCZ genes (200 kbp list) only.
