PABPN1 and facioscapulohumeral muscular dystrophy: Beyond DM1, other muscular dystrophies, such as Facioscapulohumeral Dystrophy (FSHD) and Oculopharyngeal muscular dystrophy (OPMD), show dysregulation of mitochondrial protein import genes, such as the protein translocase ANT1 and PABPN1 (part of the TIM-23 complex), respectively [62].
