The correlation of the PPP1R14A expression with MSI was also investigated in 33 types of cancer, and it indicated that BRCA, HNSC, and THCA exhibited positive correlations, while COAD, ESCA, renal carcinomas, SARC, and STAD exhibited negative correlations (Figures 13B,D). The gene discussed is PPP1R14A; the disease is renal carcinoma.
