Figure 4.
The D4Z4-adjacent p13E-11 marker sequence is more accessible to DNaseI than untranscribed gene standards and much more accessible than D4Z4 in myoblast nuclei. The size-normalized (Supplementary Table 2) percentage of DNA remaining in the parent StyI restriction fragment is shown for each examined DNA sequence in DNaseI-treated nuclei from control fetal myoblasts (A) and FSHD myoblasts (B).
