Comparative genomic hybridization analyzer view of chromosome 8. Tumors are displayed vertically and bacterial artificial chromosomes (BACS) by genome position horizontally. Low-level gains (ratio between 1.2 and 2.0) are green, high-level amplifications (ratio >2.0) are yellow, and single copy losses are red. Boxes surround common areas of aberration listed in Table 1. All BAC clone, gene and cytoband locations are given in megabase coordinates based on the UCSC genome browser (July 2003 freeze) .
