Psychiatric illnesses are disorders that affect millions worldwide. Evidence from quantitative and molecular genetics analysis suggests a strong genetic component to these disorders. There is also evidence that embryonic neurodevelopment is a key period in the progression schizophrenia. The aim of the present study was to use post-mortem human hippocampus from subjects of a variety of psychiatric phenotypes to investigate neurodevelopmentally- relevant gene expression in this region of the adult human brain. Particular interest is paid to schizophrenia risk gene DISC1; it has been shown to exhibit linkage and association to schizophrenia and is highly involved in embryonic and post natal neurodevelopmental processes. The results reported in this study indicate that DISC1 binding partners, and genes used to mark neurogenesis, can be found aberrantly expressed in schizophrenia and bipolar disorder, relative to controls. The results also suggest that DISC1 genotype may predict expression patterns of DISC1 binding partners and neurogenesis markers, irrespective of diagnosis. This may provide clues to the timing and nature of abnormal brain development in this illness and aid in development of treatment strategies.
