IGH/cMYC (MYC) Translocation, Dual Fusion
The cMYC(MYC)/IGH translocation t(8;14), and the variant forms t(2;8)(p13;q24) and t(8;22)(q24;q11), are found in Burkitt's lymphoma and mature B-cell or Burkitt's type Acute Lymphoblastic Leukaemia (ALL)1.The t(8;14) is the most common and is found in approximately 85% of patients with Burkitt's lymphoma2. While translocation breakpoints on chromosome 14 are clustered to a narrow region 5' to the intron enhancer of the immunoglobulin heavy chain, the breakpoints on chromosome 8 can occur more than 340kb upstream of MYC, with no preferential site3. The translocation brings MYC into close proximity to the IgH enhancer and results in the up-regulation of MYC4. Over expression of the transcription factor stimulates gene amplification resulting in uncontrolled cell proliferation, which usually occurs in the late event of tumour progression5.
