(in Byrd et al). Microarray gene expression analysis of chronic lymphocytic leukemia (CLL) cases with or without trisomy 12.25
The principal component analysis of the first three principal components defined by the predictor variables shows a clear separation of the cases with trisomy 12 (red symbols in the right upper quadrant) from the cases without trisomy 12 (green symbols in the lower left quadrant) indicating distinct gene expression signatures when comparing CLL groups with different genomic aberrations.
