Matched-pair analysis of tumor cells and buccal swabs from 4 patients with CLL and one patient with MCL. Chromosomes are separated by vertical lines and numbered on the left. Normal (N) and tumor (T) cells are represented in separate columns. Left panel: copy number values (CNA). Inferred copy numbers are displayed in a color-code from 0 to 5. Middle panel: copy number plot. Copy numbers are displayed from 0 to 4. The red line indicates a normal diploid copy number of 2. Right panel: LOH plot. Yellow color means retention and blue color, LOH. In the MCL sample, chromosomes 6q, 17, and 18 show complete uniparental disomy (UPD) with normal copy number.
