Figure 1. CNV analysis on metastatic KIT-mutated GIST.

Genomic region losses (red) or gains (blue) are shown for each chromosome in each patient. GIST178 had a triploid genome, so only in this case the CN=3 state was not considered altered, while regions with CN=2 were considered as LOSS of one allele and CN=4 were considered as GAIN of one copy.
