Whole-genome aCGH profiles. Comparative chromosomal CNAs in the original WM patient sample and the established MWCL-1 cell line at a 6-month passage. Note the common CNAs on chromosome 17 between all samples. Chromosomes 1 through 22, X, and Y, from p to q arm, are plotted on the x-axis from left to right. The predicted number of copies of each gene is indicated to the left of each panel.
