Figure 3From: Stability of the CpG island methylator phenotype during glioma progression and identification of methylated loci in secondary glioblastomas Hierarchical Euclidean based clustering of the 2000 most variable loci. Samples split into 2 major cluster groups containing either CIMP+ve or CIMP-ve samples (major cluster 2 and 1 respectively). Major cluster 1 split into four sub-clusters. IDH1 mutated samples are highlighted with a black box. sGBM samples are labeled with their pair number (P#) followed by L to denote late lesion. pGBM samples are labeled with respective TCGA sample names.Back to article page
