Splicing dysfunction has been observed in Alzheimer’s disease but it remains unclear whether splicing defects have a causal role. Here the authors generate a mouse model with perturbed U1 snRNP activity, recapitulating RNA splicing defects, neuron hyperexcitability, neurodegeneration and synergy with the amyloid cascade when crossed with 5xFAD mice.
