The difference in genetic alterations between CSF and primary tumor tissue samples. A The oncoprint plot of paired primary tumor tissue samples and CSF samples in 15 GCLM patients. For each gene, the top row represented primary tumor tissue samples while the bottom row represented CSF samples. B The comparison of the type of genetic alterations between primary tumor tissues and CSF. C The Venn diagrams of the detected mutations and CNVs between primary tumor tissue and CSF samples
