Fig. 1.

Representation of copy number alteration events. Patient-level individual copy number alterations are matched to gene regions in human genome (hg19). (a) Recurrent copy number alteration events. The blue segments are copy number loss, the black segments are copy number diploid and the orange segments are copy number gain. (b) Representation of copy number alteration events with numeric values. “−1” represents copy number loss, “0” represents copy number diploid and “1” represents copy number gain. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
