In truncating TP53-mut cancer types (see Figure 6(a)), we examined that MMR genes had significant positive correlation with HNSC (MLH1 correlation coefficient/P-value = 0.27/0.00096; MSH6 correlation coefficient/P-value = 0.17/0.04), LIHC (MSH2 correlation coefficient/P-value = 0.47/0.003; PMS2 correlation coefficient/p-value = 0.33/0.04; MSH6 correlation coefficient/P-value = 0.41/0.0104), and LGG (MLH1 correlation coefficient/P-value = 0.28/0.047; MSH2 correlation coefficient/P-value = 0.31/0.02; MSH6 correlation coefficient/P-value = 0.35/0.012). The gene discussed is PMS2; the disease is cancer.
