Output of the CMA algorithm results for a region located in chromosome 7q34 and the corresponding real-time PCR results.

Three fractions from the same patient are displayed. The Lymphoid is the normal reference. Blast and Erythroid serve as test samples. The log 2 ratio behaviors them are different. As normal one, the log 2 ratio of Lymphoid is closed to 0. There is a significant loss in Erythroid, but for Blast, the log 2 ratio is not low enough. The real time PCR of Lymphoid is normalized as 1. Comparing with the reference, Erythroid is concluded as copy number aberration. However, such abnormality can not be observed in Blast.
