Clustering the ALL samples on the basis of their expression levels over a cluster of 25 genes, G7 (which was obtained by the coupled two-way clustering). (Left) The resulting dendrogram; each leaf corresponds to an ALL sample, with t(4;11) ALLs colored red and CD10- ALLs rose. (Right) The expression matrix, with rows corresponding to samples and columns to genes. 13/14 of t(4;11) samples and 3/4 of CD10- ALLs are in the central cluster of samples with low expression levels.
