The analysis showed that for predicting immune scores of 20 cancer types, TASL was found in 11 cancer types (ESCA, GBM, HNSC, LGG, LUSC, OV, PAAD, SKCM, STAD, TGCT, and THCA), and CTLA-4 in 6 cancer types (CESC, HNSC, LUSC, PAAD, TGCT and THCA) and PD-1 expression in 7 cancer types (BRCA, CSC, ESCA, HNSC, LUSC, SKCM and TGCT) with high accuracy (AUC > 0.9). The gene discussed is CTLA4; the disease is cancer.
