All six molecular subtypes of gliomas, including Codel (IDH mutant-codel LGGs), G-CIMP-high (IDH mutant-non-codel glioma with higher global levels of DNA methylation), G-CIMP-low (IDH mutant-non-codel glioma with relatively low genome-wide DNA methylation), Classic-like (IDH wild type with classical gene expression signature) and Mesenchymal-like and PA-like (pilocytic astrocytoma), were represented in this dataset (Table 1). The gene discussed is IDH1; the disease is glioma.
