* All types of Burkitt lymphoma are characterized by dysregulation of the c-Myc gene by one of three chromosomal translocations. The most common variant is t(8;14), which accounts for about 85%of cases.
* Mantle cell lymphoma (MCL) is a type of non-Hodgkin’s lymphoma (NHL), comprising about 6%, Specifically, the translocation is at t(11;14)(q13;q32).
* Extranodal marginal zone lymphomas are commonly associated with chromosomal abnormalities with translocations at t(11;18)(q21;q21), t(1;14)(p22;q32), t(3;14)(p12;q32), and trisomy 3 or 18.
* The chromosomal translocation t(14;18)(q32;q21) is characteristic of follicular lymphoma and a frequent abnormality in other types of non-Hodgkin lymphoma (NHL)
