SMARCAL1 and central nervous system cancer: The findings showed that SMARCAL1 expression and TMB level were positively correlated in Glioma (R = 0.16, P < 0.001) (Fig. 7A), LUAD (R = 0.16, P < 0.001) (Fig. 7B), and KIRC (R = 0.11, P < 0.05) (Fig. 7D), but not in LIHC (R = -0.036, P = 0.49) (Fig. 7C) and UCEC (R = 0.0012, P = 0.98) (Fig. 7E), where no significant correlation was observed.
