The results showed that there was a significant negative correlation between MALT1 expression and TMB in PRAD, THCA, BRCA, CHOL, and ESCA (cor <0, p < 0.05) but a significant positive correlation between MALT1 expression and TMB in COAD, LGG, and thymoma (THYM) (cor >0, p < 0.05) (Figure 7B). This evidence concerns the gene MALT1 and thymoma.
