For lung cancer, there was one common gene (DLX4) selected by six scores; 4 genes (TP53, CCT7, ST6GAL2 and RBM10) by five scores; 16 genes (LY6G6E, STK11, MUSTN1, NF1, FBXW7, OR7C1, SLC27A1, SIRPD, CTIF, CEP250, LPA, RYR1, QRSL1, CHD3, KCNMB3) by four scores and 27 genes by three scores (Fig. 4b and Additional file 2: Table S4). This evidence concerns the gene DLX4 and lung cancer.
