In addition, BRCA (P = 0.011, Holm-adjusted Dunn's test), GBM (P = 1.18 × 10−3), LIHC (P = 0.016), LUAD (P = 0.012) and LUSC (P = 2.72 × 10−11) diploid tumors significantly overexpressed SOX2 compared with normal tissue (Figure 1B; Supplementary Table S15). The gene discussed is SOX2; the disease is glioblastoma.
