Interestingly, we also found that some FSHD myotubes contain DUX4 transcript but no LEUTX, whereas others contain no detectable DUX4 transcript with abundant signals of LEUTX and SLC34A2 transcripts (Fig 2E and S11C Fig). The gene discussed is SLC34A2; the disease is facioscapulohumeral muscular dystrophy.
