IDH1 and brain neoplasm: In conjunction with these findings, it was also observed that FABP7 expression is preferentially correlated in LGG over GBM (p < 0.05, Log2 fold-change [Log2FC]) with the mutational status of several established oncogenes (EGFR, BRAF, NF1, PDGFRA, IDH1) for which mutations are tightly associated with the development and progression of brain tumors [47] (Figure S8).
