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.

Contactin 4（Cntn4）是轴突相关黏附分子免疫球蛋白超家族的一员。近年来，在自闭症谱系障碍的多项研究中发现了CNTN4拷贝数变异。为了探索Cntn4的剂量效应，我们制造了Cntn4靶向破坏的小鼠。敲除（KO）小鼠存活，可生育，发育正常。对KO小鼠前额叶皮层和嗅球的微阵列分析显示，与野生型小鼠相比，有数百个基因的表达水平发生了改变。
