Progress in imaging the effects of psychosis susceptibility gene variants.

Genetic imaging has become an increasingly popular tool that utilizes neuroimaging techniques to investigate the impact of genetic variation on the structure, function and connectivity of the brain. Combining genetic and neuroimaging domains is a promising approach to further the understanding of the neural mechanisms involved in mediating the effect of genetic variants on psychosis risk, with the potential to explore individual vulnerability to psychiatric illness. Imaging genetics approaches have successfully been applied to a wide range of risk genes for schizophrenia.
