Fig 4. Dendrogram from unsupervised hierarchical clustering of gene expression of 17 Wilms tumours.

IGF2, refers to IGF2 status where blue = loss of imprinting, and red = loss of heterozygosity at IGF2. Rests refers to the presence of nephrogenic rests (NR) were blue = intralobar NR, red perilobar NR and purple NR of unknown type. For each gene, red boxes indicate the presence of mutation, whereas the grey box denotes gene deletion.
