CACNA1D and reading: By means of the Kaplan-Meier analysis, we found 8 overlapping DEGs (CACNA1D, DTNA, FZD3, PRR11, RPS6KA5, SERPINE1, TMEM178B, and TUBB6) in COAD (Figures 5(a)–5(h)) and 3 DEGs (PLXNA1, PTPRU, and ZFPM2) in READ which were correlated with the survival rate significantly (Figures 5(i)–5(k)).
