Genomic structure of the 18q amplicon shown by comparative genomic hybridization to microarrays in B-NHL cell lines. Only the 18q clones from the HumArray 1.14 CGH microarray are shown; a full list of these clones and the numeric results of array CGH are provided in Supplemental Table S2. Each clone contains at least one sequenced tagged site (STS), allowing linkage to the genome sequence (http://genome.cse.ucsc.edu). The order of the clones was arranged according to the April 2002 version of the draft. The array provides an average resolution of 1.4 Mb across chromosome 18. Both BCL2 and MALT1 peaks of amplification are indicated by arrows.
