Functional genomics indicate that schizophrenia may be an adult vascular-ischemic disorder

AbstractIn search for the elusive schizophrenia pathway, candidate genes for the disorder from a discovery sample were localized within the energy-delivering and ischemia protection pathway. To test the adult vascular-ischemic (AVIH) and the competing neurodevelopmental hypothesis (NDH), functional genomic analyses of practically all available schizophrenia-associated genes from candidate gene, genome-wide association and postmortem expression studies were performed. Our results indicate a significant overrepresentation of genes involved in vascular function (P<0.001), vasoregulation (that is, perivascular (P<0.001) and shear stress (P<0.01), cerebral ischemia (P<0.001), neurode…
