Mutations in BRAT1 are associated with neurodevelopmental delay and neurodegeneration. Here, the authors show that BRAT1 is a component of Integrator and is important for processing of specific RNAs. They further demonstrate that BRAT1 mutant patient-derived cells exhibit reduced levels of the Integrator catalytic subunit and increased levels of misprocessed UsnRNAs and impaired RNA processing.
