IDH1 and glioblastoma: While the GTEx samples in the cilium bicluster were enriched in specific regions of the brain from the amygdala, hypothalamus, and caudate region (Figure 1), the TCGA samples were not enriched in any particular tumor subtypes: 12 were GBM, 28 were LGG; and while seven were IDH1/2-mutated and/or 1p/19q co-deleted, 32 were wild-type and one did not have subtype information.
