Chromosomal imbalances influence the lymph node, proliferation, T-cell, and MHC class II gene-expression signatures. In each of the 4 panels, DLBCL cases are ordered according to their average expression of the respective signature genes (the case with the lowest expression appears on the left end of the spectrum). Cases with the chromosomal abnormalities shown on the right are marked with a yellow bar. Correlations with a P value less than .05 are shown. If more than one cytoband in one chromosomal arm showed a P value less than .05, the cytoband with the lowest P value is displayed.
