We carried out multivariate Cox regression analysis to identify immune-related genes in order to predict prognosis for all ccRCC samples by the formula IRGP = TMSB4Y*(-0.36) + PLAU*(-0.217) + GNAI1*(0.399) + VIM*(0.299) + CDH1*(0.258) + VAV3*(-0.351) + SEMA3G*(-0.356) + SEMA6D*(-0.431) + BMP1*(0.627) + CHGA*(0.945) + IL11*(0.683) + TSLP*(0.787) + TACR1*(0.579) + TEK*(-0.327) + THRB*(-0.621) + PRKX*(-0.486) + TNIP1*(-0.606) + GATA4*(-1.142) + SREBF2*(0.705) (each gene name in this formula represents its expression level). The gene discussed is BMP1; the disease is nonpapillary renal cell carcinoma.
