ETV5 and oligodendroglioma: RNAseq data from TCGA identified 221 differentially expressed genes in CIC mutant versus wild-type oligodendrogliomas (Figure S3F, fold cutoff of 1.5, p-value < 0.05 and FDR < 10%) amongst which the known CIC targets ETV1, ETV4, and ETV5 were significantly up-regulated in CIC-mutant cases.
