Furthermore, 16 genes (APC2, FZD3, EGFR, TGFBR1, NRAS, PIK3CA, COL4A4, IL2RB, E2F1, GNB4, KRAS, E2F3, IKBKG, SOS1, TP53, and MAPK3) are involved in pathways in cancer, while 11 genes (NRAS, PIK3CA, COL4A4, IL2RB, GNB4, KRAS, IKBKG, SOS1, TP53, EGFR, and MAPK3) are involved in PI3K-Akt signaling pathway and five genes (NRAS, PIK3CA, KRAS, MAPK12, and MAPK3) are involved in VEGF signaling pathway, demonstrating that the important genes identified by the SHAP interpretation of XAT-VAE-Cox model are linked with poor prognosis of NSCLC. The gene discussed is COL4A4; the disease is non-small cell lung carcinoma.
