Isolation of genomic DNA and array CGH analysis were performed as described in [55 (link)] using 4 × 44K whole genome oligonucleotide-based arrays (Agilent, Canada). Labeling and hybridization procedures were performed according to the instructions provided by Agilent using the SureTag DNA Labeling Kit. Slides were scanned with a G2505B Micro Array Scanner (Agilent). Feature Extraction and data analysis were carried out using the Feature Extraction and Agilent Genomic Workbench software, respectively.
