They also suggested that increased amounts of DUX4c or DUX4 proteins in FSHD muscle cells may obstruct C1QBP or other RBPs from performing their normal functions and impede the process of muscle regeneration, exacerbating the muscle pathology activated by DUX4 [123]. The gene discussed is DUX4L9; the disease is facioscapulohumeral muscular dystrophy.
