Myotonic dystrophy type 1 affects both muscle and neuronal function, but its synaptic pathology is poorly understood. Here, the authors show that upregulation of FasII (NCAM1) in both pre- and postsynaptic cells synergistically drives neuropathological and behavioral DM1 phenotypes, which can be rescued by FasII knockdown or specific isoform modulation.
