In this study, the authors show that Dscam, a gene that has been implicated in Down syndrome, is targeted by the translation suppressor and Fragile X–linked protein FMRP. Loss of FMRP or overexpression of Dscam in Drosophila led to synaptic targeting errors and an impairment in perception of mechanical stimuli.
