Mutation characterization and enrichment analysis of molecular subtypes. (A) Somatic mutation analysis of different molecular subtypes in the TCGA-LIHC cohort. (B–D) GSVA enrichment analysis of different molecular subtypes based on KEGG gene sets. Cluster A versus Cluster B (B), Cluster A versus Cluster C (C), Cluster B versus Cluster C (D). (E–G) Hallmark-based enrichment analysis of different molecular subtypes of GSVA. Cluster A versus Cluster B (E), Cluster A versus Cluster C (F), Cluster B versus Cluster C (G).
