Intermediate phenotypes in psychiatric disorders

Roberta Rasetti, Daniel R Weinberger
2011 Current Opinion in Genetics and Development  
Neuroimaging-based intermediate phenotypes have emerged as particularly promising because they map risk associated gene effects onto physiological processes in brain that are altered in patients and in  ...  The small effect size of most individual risk factors for psychiatric disorders likely reflects biological heterogeneity and diagnostic imprecision, which has encouraged genetic studies of intermediate  ...  Acknowledgments This research was supported by the Intramural Research Program of the National Institute of Mental Health, National Institutes of Health.

Brain Structure and Function Changes During the Development of Schizophrenia: The Evidence From Studies of Subjects at Increased Genetic Risk

S. M. Lawrie, A. M. McIntosh, J. Hall, D. G.C. Owens, E. C. Johnstone
2007 Schizophrenia Bulletin  
This article reviews the evidence for changes in the structure and function of the brain in subjects at high risk of schizophrenia for genetic reasons during the genesis of the disorder.  ...  We conclude by quoting our own and others' imaging studies of the associations of genetic and other risk factors for schizophrenia, including stressful life events and cannabis use, which provide mechanistic  ...  PFC (DLPFC) on working memory tasks in relatives vs CONs 40-43 -whereas only one small study of unaffected twins has not. 44 In 3 of the studies, there were no significant performance differences observed  ...

Schizophrenia

Paul D. Morrison, Robin M. Murray
2005 Current Biology  
A very interesting recent finding is that variation in the COMT gene, mentioned earlier, modulates the risk conferred by cannabis.  ...  Individually, each gene (and environmental risk factor) has a small effect size; for example, the relative risk for those carrying the respective risk haplotypes of neuregulin1 and dysbindin is less than  ...  The editors of Current Biology welcome correspondence on any article in the journal, but reserve the right to reduce the length of any letter to be published.  ...
