Erroneous class switching and false VDJ recombination: molecular dissection of t(8;14)/MYC-IGH translocations in Burkitt-type lymphoblastic leukemia/B-cell lymphoma..     ///    "Using long-distance PCR for t(8;14)/MYC-IGH fusion, we investigated bone marrow, peripheral blood and a few other samples with suspected Burkitt-ALL or mature B-ALL and identified 133 MYC-IGH-positive cases. "    ///    This detailed and extensive molecular analysis illustrates the molecular complexity of the MYC-IGH translocations and the detected distribution of breakpoints provides additional evidence that this translocation results from failed switch and VDJ recombinations.
