ABL1 and mature T-cell and NK-cell non-Hodgkin lymphoma: Thus, we quantified the transcripts of the two translocations by qRT-PCR using two primer pairs for each fusion (qBCR_F1, qABL_R1, qBCR_F2, qABL_R2, X;14_F1, X;14_R1, X;14_F2, X;14_R2) and the SybrGreen methodology on both diagnostic samples and found that the expression level of the t(X;14) product in the diagnostic CML sample was about 4% of the expression of the BCR-ABL1 fusion transcript in the same sample, whereas the expression of BCR-ABL1 in the diagnostic PTCL sample was more than 10 times less (Fig. 2B).
