IGL Breakapart LPH033

Translocations involving the immunoglobulin loci are recurring events in various subtypes of B cell lymphomas. In addition to translocations involving the IGH locus, variant translocations have been described in 5-10% of B cell neoplasms involving either the immunoglobulin kappa (IGK) light chain or the lambda light chain (IGL). The best known translocations involving IG light chain loci are the variant Burkitt's translocations t(2;8)(p12;q24) and t(8;22)(q24;q11) present in up to 25% of all Burkitt's lymphomas.
