Combination of copy number alteration (CNA) and allele disequilibrium (AD) data for the 22 GIST samples. For each tumor, copy number abnormalities and allele disequilibria are represented in two columns by color code bars. The corrected CNA data (after FISH verification) for tumors #1C2, #15C2 and #20 s2 are presented. The genetic deletions and gains are represented in green and red, respectively. Two copies without LOH are represented in white, and regions of cnLOH are in yellow. The level of loss of allele disequilibrium is indicated in grey. Each line corresponds to a mean value of 100 consecutive SNP. Non-continuous lines indicate the centromeres. Chromosomes are indicated in the first column on the left.
