Schematic representation of TCRβ-oncogene translocations. Shown are schematic representations of TCRβ-oncogene translocations: TCRβ-LMO1 (A), TCRβ-LMO2 (B), TCRβ-TLX1 (C), TCRβ-MYB (D), and TCRβ-HOXA (E). Both translocation derivatives are represented. Arrowheads indicate the relative position of breakpoints within the oncogene. Bold and thin bars depict the oncogene locus and the chromosome 7q35 TCRβ locus, respectively.
