Magdalena Götz, Stephen Robertson and colleagues show that biallelic mutations in DCHS1 and FAT4 cause a multisystem disorder that includes periventricular neuronal heterotopia. They further show that reducing expression of Dchs1 and Fat4 in mouse embryonic neuroepithelium causes an increase in progenitor cell numbers and reduced neuronal differentiation, resulting in heterotopic accumulation of cells below the neuronal layers in the neocortex.
