Using the Kaplan–Meier plots, we could establish that the expression of KCNAB2, KCNJ8, KCNMB4, and SCN9A appeared significantly associated with a CRC poor prognosis in at least one of the comparisons made (2 groups or upper and lower quartile) and using OS or DSSR data (OS/2-groups Figure 8a, OS/quartile Figure 8b, DSSR/2-groups Figure 8c, DSSR/quartiles Figure 8d). Here, KCNMB4 is linked to colorectal carcinoma.
