Summary figures for SE regions near VMP1/MIR21 (Chr 17), SUMO1P1 (Chr 20), and PVT1 (Chr 8) are shown as representative examples from cluster A, B, and D, respectively, showing higher accessibility in non-basal compared with basal breast tumor samples (Supplementary Fig. S5D). Here, PVT1 is linked to breast neoplasm.
