Figure 4.
Ideogram and microarray CGH chromosome plots of chromosome 4, in which PDGFRA gene is located, for a case without (A) and other with (B) PDGFRA amplification as defined by QPCR. Log2 ratios are plotted on the x axis against each clone according to genomic location on the y axis. The centromere is represented by a horizontal dotted line. Vertical dashed lines correspond to log2 ratios of 0.12 (green) and −0.12 (red). Grey dots: Log2 ratios; Blue dots: aws-smoothed Log2 ratios. The colour reproduction of this figure is available on the html full text version of the article.
