- CD 8 expression (40% as opposed to 4% in myc-positive BL) [9]
Immunohistochemistry:
Chromosomal Rearrangements (Gene Fusions)
BLL-11q has no known gene fusions at this time.
Chromosomal Rearrangement | Genes in Fusion (5’ or 3’ Segments) | Pathogenic Derivative | Prevalence | Diagnostic Significance (Yes, No or Unknown) | Prognostic Significance (Yes, No or Unknown) | Therapeutic Significance (Yes, No or Unknown) | Notes |
---|---|---|---|---|---|---|---|
Individual Region Genomic Gain / Loss / LOH
The table below represents the smallest reported minimal lost region and smallest reported minimal gain region. Other larger MGR and MLR have been reported.[10] [11]
Chr # | Gain / Loss / Amp / LOH | Minimal Region Genomic Coordinates [Genome Build] | Minimal Region Cytoband | Diagnostic Significance (Yes, No or Unknown) | Prognostic Significance (Yes, No or Unknown) | Therapeutic Significance (Yes, No or Unknown) | Notes |

Characteristic Chromosomal Patterns
- Research up until this point has revealed no conservative breakpoints. [12]
Chromosomal Pattern | Diagnostic Significance (Yes, No or Unknown) | Prognostic Significance (Yes, No or Unknown) | Therapeutic Significance (Yes, No or Unknown) | Notes |
---|---|---|---|---|
proximal 11q duplications range in size | yes | unknown | unknown | The characteristic gains combined with the terminal deletions can occur in the context of myc-positive BL and other myc-negative HGBCLs. The absence of a MYC translocation/amplification in association with this chromosomal pattern is critical to the provisional diagnosis of BLL-11q and may have prognostic and therapeutic implications, which are further discussed below. At least one case has been identified with only proximal gains in the context of UPD.[12] |
terminal 11q deletions range in size | yes | unknown | unknown | |
5q21.3q32 gain and 6q12.1-q21 loss [13][8] | unknown | unknown | unknown | Noted to be recurrently concomitantly present with the characteristic proximal duplications and deletions that define BLL, 11q.[13] |
Notably, no 1q21 abnormalities were found in myc-negative, 11q positive cases. [7][8]
Gene Mutations (SNV / INDEL)
- Studies suggest an overall unique mutational profile, with little to no overlap with commonly mutated genes in DLCBL and BL, respectively. Notably, recurrent mutations in BL such as ID3, TCF3, and CCND3 were not present. [8] [14]
- Mutations listed below where noted to be recurrent in BLL-11q cases. Bold genes have also been found recurrently mutated in DLCBL.
Recurrently mutated genes in BLL-11q with known mechanisms that may contribute to pathogenesis.
Gene; Genetic Alteration | Presumed Mechanism (Tumor Suppressor Gene [TSG] / Oncogene / Other) | Prevalence (COSMIC / TCGA / Other) | Concomitant Mutations | Mutually Exclusive Mutations | Diagnostic Significance (Yes, No or Unknown) | Prognostic Significance (Yes, No or Unknown) | Therapeutic Significance (Yes, No or Unknown) | Notes |
---|---|---|---|---|---|---|---|---|
BTG2; variable potential LOF mutations
|
tumor suppressor gene via inhibition of CCND1 via pRb[8] | 4/11 cases[8]
|
none known | none known | unknown | unknown | unknown | |
NFRKB **located in region of terminal deletion
|
gene associated with INO80 complex[14] | 4/15 cases[14] | none known | none known | unknown | unknown | unknown | NFRKB is within the terminal deletion region, so these mutations would result in a biallelic loss. [14]

Note: A more extensive list of mutations can be found in cBioportal (https://www.cbioportal.org/), COSMIC (https://cancer.sanger.ac.uk/cosmic), ICGC (https://dcc.icgc.org/) and/or other databases. When applicable, gene-specific pages within the CCGA site directly link to pertinent external content.
Epigenomic Alterations
- KMT2A has been found to be duplicated and occasionally amplified in numerous cases of BLL-11q[12]
- functions to methylate histones[15]
- Found to have mutations in EP300, HIST1H1D, HIST1H2BC, CREBBP, KMT2C, EZH2, ARID1A, KMT2D[8]
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. Still, it is presumed to be a a product of dosage effects produced by the more varied proximal duplications and more consistent terminal deletions.[12]
- Genes found recurrently in minimal duplication region: IL10RA; TMPRSS4; SCN4B; AMICA1; MPZL3; CD3E; CD3D; UBE4A; ATP5L; KMT2A; TTC36, TMEM25, IFT46; ARCN1 [10] [12]
- Genes found recurrently in terminal deleted region: ETS1; FLT1; KCNJ5; C11orf45; TP53AIP1 [10] [12]
GENES with PROPOSED/KNOWN CANCER ASSOCIATIONS
Gene; Genetic Alteration | Pathway | Pathophysiologic Outcome |
---|---|---|
IL10RA; Duplication | insulin receptor substrate-2/PI 3-kinase/AKT pathway[17] | increase survival of progenitor myeloid cells[17] |
KMT2A; Duplication | methylation of histones (turns off genes)[15] | amplification noted to be associated with bulky BLL-11q tumors >20 cm, mainly located in the retroperitoneum[12] |
USP2; duplication (found 1x) [12] | deubiquitinase known to target proteins such as MDM2 (udiquinates p53), MDM4, and CCND1[18] | increased degradation of p53 (less tumor suppressor) and more CCND1-->increased movement from G1 to synthesis[18] |
NFRKB; deleted[14] | encodes a nuclear factor involved with the INO80 complex[14] | altered transcriptional regulation [14] |
Genetic Diagnostic Testing Methods
- Conventional cytogenetics (karyotyping) + FISH using MYC break-apart probe to rule out MYC translocation [13] [3]
- Chromosomal microarray analysis [8] [3]
Familial Forms
- None known

Clinical Implications
- Look for 11q aberration if Myc negative lymphoma with morphology reminiscent of BL, DLBCL, or HGBCL [3]
- 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 [2] [4] [5]
- BLL-11q patients treated with R-CHOP (DLBCL treatment) have a higher risk of relapse than those treated with traditional BL treatment [6] [7]
Tentatively appears to portend a better prognosis with high likelihood of years of remission [3] [8] [6][2]
