Using the “pathological staging chart” module of GEPIA2, significant correlations between LRFN4 expression and pathological stages were identified in adrenocortical carcinoma (ACC), lung adenocarcinoma (LUAD), kidney renal clear cell carcinoma (KIRC), lung squamous cell carcinoma (LUSC), and ovarian cancer (OV) (Figure 4). The gene discussed is LRFN4; the disease is adrenal cortex carcinoma.
