On the 19.7% subset of Yao et al. (2014) (30) DUX4 target gene-positive FSHD cells, the PAX7 target gene repression signature was an equivalent biomarker to the Yao et al. (2014) (30) DUX4 target gene expression biomarker (PAX7 AUC = 0.660, DUX4 AUC = 0.660, DeLong’s P = 0.99; Fig. 4B). The gene discussed is DUX4; the disease is facioscapulohumeral muscular dystrophy.
