Figure 1

Unsupervised hierarchical clustering for the selection of differentially expressed genes in GIST tumours according to KIT mutation. Across the top, individual tumour samples are arrayed in a column (upper: blue - KIT mutation; red - PDGFRA mutation; gray- no mutation found; lower: green - low KIT expression/high PDGFRA expression; yellow- high KIT expression/low PDGFRA expression; dark gray- high KIT/PDGFRA expression); on the left side, 311 individual probe sets differentiating tumours in accordance with the mutation are shown in rows. The colour in each cell reflects the level of expression of the corresponding probe set in the corresponding array sample relative to its mean level of expression estimated for the entire set of samples. Red indicates expression levels greater than the mean, and green indicates lower than the mean.
