SNURPORTIN-1, encoded by the SNUPN gene, plays a key role in the nuclear import of spliceosomal small nuclear ribonucleoproteins, however its physiological function remains unclear. Here the authors report that recessive SNUPN mutations cause a distinct subtype of childhood muscular dystrophy and reveal SNURPORTIN-1’s role in muscle homeostasis, offering insights for new therapeutic strategies.
