  • KLF15 is a specific activator of FRG2 (the regulation of FRG2 expression by KLF15 is direct rather than through the action of myogenic factors)

  • when overexpressed, KLF15 activated the D4Z4 enhancer and led to overexpression of DUX4L9 and FRG2
    • Other regulated by MECP2 which interacts directly with YY1
