The authors show that mice lacking Fragile X Mental Retardation Protein (FMRP) have disrupted neuronal migration during cortical development. FMRP-deficient mice also show altered excitatory-to-inhibitory balance early postnatally. They identify N-cadherin as a target of FMRP and show that re-expressing N-cadherin can rescue these phenotypes in FMRP-deficient mice.
