Validation of the selected genes for TEL/AML1 using Set-B microarray data. (A) Hierarchical clustering analyses (Euclidean distance and average linkage) of Set-B microarray data using the 14 selected genes for TEL/AML1. Patients are segregated according to the presence or absence of the TEL/AML1 rearrangement. (B) Support tree of Set-A and Set-B patients using the 14 selected genes for TEL/AML1. Two branches clearly distinguished TEL/AML1-positive ALL and TEL/AML1-negative ALL with 100% of reproducibility when resampling with replacement was conducted on experiments and genes for 100 iterations. The expression levels of the RUNX1 gene can explain the clustering of patients 9 and 17.
