The relation between FDX1 expression and TMB was significant (p < 0.05), and data were available for 10 of 32 cancer types (ESCA, HNSC, KIRC, LGG, LUAD, LUSC, STAD, THCA, THYM, and UCEC), among which ESCA, LGG, and STAD coefficients were the highest, whereas KIRC, LUAD, and THCA coefficients were the lowest (Figure 9A). This evidence concerns the gene FDX1 and cancer.
