In the version of this Article initially published, Figs 6a and 6c contained panels that were inadvertently duplicated. In Fig. 6a, the panels in the right-hand column (Distal) corresponding to αSETDB1, αCHD7 and αNLK were duplicated. In Fig 6c, the panels in both the left (Proximal) and right (Distal) columns corresponding to αH3K9me2, αH3K9me3 and αSETDB1 were duplicated. The correct versions of Figs 6a and 6c are provided below. The original conclusions of the study are unchanged.
