Figure 1.

Recurrent genomic abnormalities in 49 primary breast tumor samples revealed by array CGH. Frequencies of genome copy number gains and losses are plotted as a function of genome location with chromosome 1pter to the left and chromosomes 22 and X to the right. Vertical lines indicate chromosome boundaries and vertical dashed lines indicate centromere locations. Green and red columns indicate frequencies of tumors showing copy number increases and decreases, respectively.
