NOTE: T-ALL: T-cell ALL samples; B-ALL: B-cell ALL samples; Ph+: all samples containing the Philadelphia chromosome; Ph−: samples not containing the Philadelphia chromosome; SD: standard deviation.

>> normal: sample values with high expression of CFTR based on the range of expression observed in normal human MNCs;

≤ normal: sample values with low expression of CFTR based on the range of expression observed in normal human MNCs.
