Research Abstract

Contactin 4(Cntn4) is a member of the immunoglobulin super family of axon associated adhesion molecule. Recently, copy number variations of CNTN4 have been detected in several studies on autism spectrum disorders. To explore the dosage effect of Cntn4, we generated mice with targeted disruption of Cntn4. The knockout(KO) mice were viable and fertile and developed normally. Microarray analyses of the prefrontal cortex and olfactory bulb of KO mice revealed several hundred genes with altered expression levels in comparison with the wild type mice.
