CD4 and adrenal cortex carcinoma: We calculated the risk score (RS) as: RS = −0.398*HLA‐DPA1‐0.656*RAC2‐0.247*HLA‐DRB5‐0.246*HPGDS + 0.985*PTPRB + 0.692*HCK + 0.092*HLA‐DOA + 0.005*RAB37 + 0.016*FOLR2‐0.538*GRAP2‐0.554*TACR1‐1.981*TBXAS1 + 0.102*HLA‐DRA + 1.802*CD53 + 1.545*LAIR1‐0.035*WAS‐0.645*CD93‐0.33*CD4 for all 79 ACC patients, and divided those patients into low‐RS group (n = 39) and high‐RS group (n = 40) (Table S4).
