CDK12 and neoplasm: Through the analysis of CDK12 expression and its correlation with TMB (Fig.11A) and precise radar chart analysis (Fig.11C), it was observed that in seven types of tumours, namely, THYM, STAD, LUAD, LGG, SKCM, HNSC, and THCA, the expression level of CDK12 was significantly correlated with TMB.
