Plot of copy number variations by chromosomes that are color-coded. Sex chromosomes are excluded from the analysis. The vertical axis is the ratio of number of reads for a specimen to a panel of normal samples in log base 2 scales. A value of 0 denotes no difference from normal (diploid). When the sample contains 100% tumor cells, a value of − 1 is equal to 1 copy loss, and 0.58 is equal to 1 copy gain. The arrow shows the MYCN amplified region
