Genomic imbalances detected in individual tumor samples. Gains (red) and losses (blue) of genomic material were detected in all tumor samples by SNP array analysis. Each row corresponds to a unique sample and each column represents a specific chromosome. Chondroid and classic chordoma samples have been grouped to facilitate comparison. Note the acquisition of chromosome 3 loss and the similarity of gains and losses in the recurrent tumor sample (CHD20) to the primary tumor sample (CHD19).
