Copy number profile of 53 t(14;18)⁻FLs. Global copy number (top panel) and copy number neutral loss of heterozygosity (CNN-LOH; bottom panel) profile. The x-axis depicts chromosome positions with dotted lines pointing out centromeres. The y-axis indicates frequency of the genomic aberration among the analyzed cases. Each probe is aligned with chromosomes from 1 to Y and p to q. Gains are depicted in blue and losses in red, and regions of CNN-LOH are represented in yellow. Recurrent CN and CNN-LOH regions (>15% of cases) are indicated.
