Moreover, we found that IDH1 wild-type gliomas showed a higher expression of BCAT1 than mutant types in both TCGA and CGGA datasets (Figure 2G, 2H), and further internal comparison of IDH1 mutant gliomas showed that 1p19q codeleted IDH1 mutant gliomas owns a lower expression than non codeleted 1p19q forms with a significant difference in the CGGA dataset (Figure 2I, 2J). The gene discussed is BCAT1; the disease is glioma.
