On the basis of the 451 key DEGs identified, we performed univariate Cox regression analysis separately using the tumor samples of the training set and validation set, resulting in the identification of 13 genes (BANF1, CDK2AP2, CYBA, DDT, EPS8, LRIG1, MRPL4, NUCB2, PAF1, PMP22, RABGAP1L, S100A13 and USO1). The gene discussed is BANF1; the disease is neoplasm.
