Unsupervised classification of uveal melanoma samples based on gene expression profiling. Classification of 91 uveal melanoma samples using the 1138-probe sets identified as differentially expressed between the 46 liver metastatic samples and the 45 non-metastatic samples. Expression data are depicted as a data matrix where each row represents a gene and each column represents a sample. Expression levels are depicted according to the color scale shown at the top. Red and green indicate expression levels, respectively, above and below the median. The magnitude of deviation from the median is represented by the color saturation.
