  "summary": "Loss-of-function variants in SNUPN, encoding the nuclear import factor Snurportin-1 (SPN1) required for spliceosomal small nuclear ribonucleoprotein (snRNP) transport, cause a recently described form of limb-girdle muscular dystrophy (LGMD). However, the role of SPN1 in skeletal muscle homeostasis remains poorly understood, in part due to the lack of a suitable in vivo model. Here, we generated a…",
