Figure 5

Glioma Copy Number Variation In Chromosome 4q12. Segmentation analysis depicts 4q12 (x-axis) amplification and deletion events representing 141 glioma tumors (y-axis). Exons for known genes are highlighted as blue boxes, with introns depicted as blue lines between boxes. The glioma oncogene PDGFRA is the focus of 4q12 amplification, consistent with what is normally seen in the literature.
