Figure 1From: High-density SNP arrays improve detection of HER2 amplification and polyploidy in breast tumorsSchematic representation of copy number variations across chromosome 17. The percentiles of SNP samples with amplification or deletion among the breast tumor samples analysed on SNP 500Â K are indicated in red and blue, respectively. The positions of HER2 and the smallest amplicon containing 9 full-length genes (from 37642255 to 37970066 based on Hg19) are indicated.Back to article page
