Further analysis of PTPN11 expression revealed positive correlations with MSI in nine types of cancer, including ACC, MESO, LUSC, READ, UCEC, TGCT, OV, COAD, and LUAD; and negative correlations with MSI in SKCM and DLBC (Figure 8B and Supplementary Figure 1B). This evidence concerns the gene PTPN11 and cancer.
