Fig. 5: Pathway differences between CSF and primary lesions.

A Remarkable enrichment of KEGG pathways in each group according to FDR < 0.1. The vertical axis indicates gene count. Gene count means the number of mutated genes enriched in one term. B Heatmap of alteration frequency of identified pathways. The horizontal axis represents signal pathways, and the figures indicate mutation percentages. Differences with significant P values are labeled (two-sided Fisher’s exact test). **P < 0.01, ***P < 0.001. C Gene alterations (including SNV and CNV) of highly frequent and unique pathways in CSF samples. The vertical axis shows gene mutation frequency.
