nervous system

nervous system phenotype ( J:215740 )

N	• layer formation in the somatosensory cortex is normal

abnormal neuronal migration ( J:215740 )

• fewer GAD65 and GAD67 positive cells enter the pallium and top of the cerebral cortex at E14.5 (impaired tangential migration of cortical inhibitory interneuron precursors)

• doublecortin positive subventricular zone cells at higher levels at the posterior of the rostral migratory stream than at the anterior end

• double cortin positive cells are disorganized on the lateral ventricle wall before migration

• migration of cells out of explants cultured in Matrigel is reduced

• migration of cells is slower
