Shared and emerging chromosome copy number abnormalities. Whole chromosome plots of chromosomes 1, 3, 8, and 22 are shown for the 4 samples. Arrows point out examples of gains or losses that appear uniformly across all 4 samples (chromosomes 3, 8, and 22), or are acquired during the course of disease progression (chromosome 1). The predicted number of gene copies is indicated on the top of each panel.
