Jens Lykke-Andersen, Frank Baas, Joseph Gleeson and colleagues report that mutations in the 3′ exonuclease TOE1 cause pontocerebellar hypoplasia type 7. They further show that these mutations result in the accumulation of incompletely processed small nuclear RNAs, leading to severe, early-onset neurodegeneration.
