Facioscapulohumeral muscular dystrophy (FSHD) is an autosomal dominant skeletal muscle disorder with a prevalence of approximately 1 in 8,000. The disorder is driven by aberrant expression of double homeodomain protein 4 (DUX4) within the D4Z4 macrosatellite array. Currently, effective treatments for FSHD are lacking. Strategies aimed at reducing DUX4 expression could hold promise as potential therapeutic approaches for FSHD.
