DNA copy number data from patient #63. Copy number plot with the x-axis denoting each point across the genome - each chromosome is highlighted in a different colour starting with chromosome 1 on the left side. Y-axis enumerates the log-2 copy number value at each point across the genome. Red arrow indicates gene amplification highlighted in this manuscript. Normal ERRB2 copy number in primary tumour (log₂ copy number ratio 0.34) and amplification of E2F3 in the metastasis (log₂ copy number ratio 1.19).
