Concordance of EGFR-activating mutations in CSF samples with matched PLA. Oncoprint of the multiple genetic alterations from the 9 matched CSF-PLA cases are shown. The three top bars indicate the number of mutations, age, and MAF in matched samples. The left side-bar presents names of the detected genes in matched CSF-PLA pairs, and the right side-bar demonstrates the number of specific mutations in patients. Colour keys represent the variant type of the relative gene. MAF: mutant allele frequency. CSF: cerebrospinal fluid. PLA plasma
