Using our fusion gene database [17, 26, 60], we identified gene–gene fusions in cfDNA and tumour DNA, such as KDR‐PDGFRA (8%), and NCDN‐PDGFRA (40%) that correspond to the previously reported alterations of PDGFRA in GBM (43% of all our samples). This evidence concerns the gene KDR and glioblastoma.
