Integration of Copy Number and LOH. The integration was performed using the data generated using the criteria outlined for LOH and CNA described in the Materials and methods. The length of the bars indicates the number of samples. The LOH events close to the centromeres of chromosomes 8, 16 and X are the most frequent LOH events but not certifiable due to few probes in those regions. Copy number loss with LOH is detected at 8p12, Xp24 and Xp25. The other detected regions are copy neutral events.
