Figure 3

Significant differences in copy number change detected at seven loci for gain and three loci for loss among twenty-six selected loci. Colors of the stacked bars represent copy number: orange, 3,4 copies; red, ≥ 5 copies; blue, 1 copy loss (heterozygous deletion), light green: 2 copy losses (homozygous deletion). 17q12, 17q25.1 show remarkable differences in copy number gain between ALK fusion-positive and -negative tumours.
