Schematic representation of TCRα/δ-oncogene translocations. (A-D) Shown are schematic representations of TCRα/δ-oncogene translocations: TCRα/δ-TLX1 (A), TCRα/δ-MYC (B), TCRα/δ-LMO2 (C), and TCRα/δ-TAL1 (D). Both translocation derivatives are represented, with corresponding T-ALL unique patient numbers. Arrowheads indicate the relative positions of breakpoints within the oncogene. Bold and thin bars depict the oncogene locus and chromosome 14q11 TCRα/δ, respectively.
