IDH1 and neoplasm: Although CIC was not included in the above analyses since it was mutated only in LGG, due to its important role in LGG tumors, we examined how CIC regulates expressions of target genes and found that chromatin remodeling genes in list A were significantly enriched among dysregulated target genes, in both full LGG tumor samples and in stratified samples by IDH1 mutation status (Additional file 9: Table S7).
