For example, Xu and Chen (30) utilized a six AG-based pattern (APOC3, EPOR, H2AFX, MXD1, PLCG2, and YWHAZ) to structure a risk model that could efficiently stratify the existing cases in high- and low-risk groups in terms of OS in lung adenocarcinoma (LUAD). The gene discussed is PLCG2; the disease is lung adenocarcinoma.
