After years of frustration, the search for genes impacting on schizophrenia is now undergoing some exciting developments. Several proposals of susceptibility genes have been able to be supported by replications. Thus, there are now at least three very strong candidates: the gene for dysbindin (DTNBP1), the gene for neuregulin-1 (NRG1), and a less well-understood gene locus, G72/G30, which are l...

Aberrant neuregulin-1 (NRG1) signals are suggested to associate with the neuropathophysiology of schizophrenia. Employing a mouse schizophrenia model established by neonatal neuregulin-1 challenge, we analysed postpubertal consequence of the NRG1 pretreatment for the electrophysiological property of nigral dopamine neurons. In vivo single unit recordings from anaesthetized NRG1-pretreated mice ...

The neuregulin 1 (NRG1) gene has been the subject of considerable excitement within the psychiatric genetics literature since it was originally identified as a potential susceptibility locus for schizophrenia. Here we provide an update of our first meta-analysis of this association. Case-control and family-based genetic association studies of the NRG1 gene in healthy control groups and clinical...
