In B‐cell NHLs, disease subtype‐specific chromosomal abnormalities are strongly associated with disease development, such as translocation t(14;18) involving BCL2 gene rearrangement in follicular lymphoma 5, 6, t(11;14) involving Cyclin D1 (CCND1) gene rearrangement in mantle cell lymphoma 7, or t(8;14) involving c‐MYC gene rearrangement in Burkitt lymphoma 8, 9. Here, BCL2 is linked to B-cell non-Hodgkin lymphoma.
