The mouse Wnt/PCP protein Vangl2 is necessary for migration of facial branchiomotor neurons, and functions independently of Dishevelled

► We examined facial branchiomotor (FBM) neuron migration in several Wnt/PCP mutants. ► Caudal migration lost in Vangl2 and Ptk7 mutants, but not in Dvl1/2 double mutants. ► Caudal migration of FBM neurons is independent of Dvl function. ► Rostral migration of FBM neurons, which is normally suppressed, is Dvl-dependent.
