Burkitt lymphoma is characterised by translocation t(8;14). The oncogene translocated to the IGH locus on chromosome 14 is:
- A BCL2
- B CCND1 (cyclin D1)
- C MYC ✓
- D BCL6
Explanation
In t(8;14)(q24;q32), the MYC proto-oncogene on chromosome 8 is juxtaposed to the immunoglobulin heavy chain (IGH) enhancer on chromosome 14, causing constitutive MYC overexpression that drives highly aggressive B-cell proliferation. Variant translocations t(2;8) and t(8;22) involve kappa and lambda light chain loci respectively. BCL2 translocation t(14;18) is the hallmark of follicular lymphoma.
