==Genes and Main Pathways Involved==

*Given the notable variations in size of the duplicated and deleted regions of BLL-11q, pathogenesis appears to be complex and remains to be elucidated.

Clinical Implications


*Look for 11q aberration if Myc negative lymphoma with morphology reminiscent of BL, DLBCL, or HGBCL <ref name=":6" />
*Attend to associated chromosomal and mutational abnormalities of other aggressive B-cell lymphomas, ensuring their absence before diagnosis of BLL-11q, since BLL-11q may represent <ref name=":3" /> <ref name=":8" /> <ref>{{Cite journal|last=Grygalewicz|first=Beata|last2=Woroniecka|first2=Renata|last3=Rymkiewicz|first3=Grzegorz|last4=Rygier|first4=Jolanta|last5=Malawska|first5=Natalia|last6=Blachnio|first6=Katarzyna|last7=Bystydzienski|first7=Zbigniew|last8=Borysiuk|first8=Anita|last9=Nowakowska|first9=Beata|date=2020-07-01|title=Genetic progression of post-transplant Burkitt-like lymphoma case with 11q-Gain/Loss and MYC amplification|url=https://www.cancergeneticsjournal.org/article/S2210-7762(20)30236-2/abstract|journal=Cancer Genetics|language=English|volume=245|pages=1–5|doi=10.1016/j.cancergen.2020.05.001|issn=2210-7762|pmid=32531723}}</ref>
