BCL2 and mantle cell lymphoma: These translocations are often characteristic for certain B-cell Non-Hodgkin’s lymphoma entities: In mantle cell lymphoma (MCL) the gene encoding cyclin D1 (CCND1) is characteristically translocated into the IgH locus (t(11;14) (q13;q32)) and in follicular lymphoma (FL) BCL2-IgH translocations (t(14;18)(q31;q21)) are seen in more than 90% of cases (6).
