Genetic variation of ferroptosis genes. (A) The expression of ferroptosis genes in TCGA tumor samples and normal samples. (B) The distribution and type of mutations in ferroptosis genes. (C) The frequency of occurrence of CNVs in ferroptosis genes, with blue indicating deletions and orange indicating amplifications. (D) The chromosomal location of 60 ferroptosis genes. (E) The PCA results of ferroptosis genes in TCGA samples. ns (not significant) stands for P>0.05, *, P<0.05; **, P<0.01; ***, P<0.001; ****, P<0.0001. TCGA, The Cancer Genome Atlas; CNV, copy number variation; PCA, principle component analysis.
