Note The t(10;14)(q24.31;q11) in T-ALL involves the gene TLX1 at the band 10q24.31 and not NFKB2 at band 10q24.32 (Neri et al., 1991).

Clinics and Pathology

Disease B-cell lymphomas: The band 10q24 is involved in 7% of low-grade B-cell lymphomas, splenic marginal zone B-cell lymphomas in particular (Solé et al., 2001; Lefebvre et al., 2007, Nadal, unpublished observation) and also, but less frequently, in intermediate and high risk lymphomas (Neri et al., 1991).
Other chronic lympho proliferative diseases: Multiple myeloma (Migliazza et al., 1994; Mohamed et al.), chronic lymphocytic leukemia (CLL) (Migliazza, 1994)
Prognosis Unknown.


Cytogenetics Morphological The t(10;14)(q24;q32) is a rare but recurrent abnormality in lymphoid malignancies.
Additional anomalies The following known recurrent abnormalities were found in one case each: +3, +7, and +12.

Genes involved and Proteins

Gene NameNFKB2
Location 10q24.32
Note Alias: LYT-10, NF-kB2, p105, p49/p100, p52
Dna / Rna NFKB2 gene is a member of NFKB gene family. NFKB2 gene encodes for the precursor p100/p52 from which the active p52 subunit is formed.
Protein P52 is a member of the NFKB family transcription factors that are formed by the homo/dimerization of the subunits of the NFKB family. After dimerization with the subunit RELB, P52 migrates to the nucleus where they activate the transcription of target genes.
Localization: cytosol for p100 product and nucleus for the final product p52 after activation
P52 is a component of the non-canonical NF-KB pathway which plays a role in the control of the last stages of B-Cells development (maintenance of the Germinal Center (GC) reaction and Plasma cell development) (Shaffer et al., 2012; De Silva et al., 2017).
Gene NameIGH (Immunoglobulin Heavy chain)
Location 14q32

Result of the chromosomal anomaly

Hybrid gene
Description t(10;14)(q24;q32) translocation juxtaposes IGH constant region gene with NFKB2 gene (Neri et al., 1991). The fusion gene NFKB2/IGH results in the constitutional activation of the non-canonical NFKB pathway. The reciprocal fusion gene IGH/NFKB2 is not transcribed.
Fusion Protein
Note NFKB2 gene encodes for the protein P52 which contains a DNA binding domain and an Ankyrin domain. The Ankyrin domain is thought to retain p100/P52 in the cytoplasm and thus prevent the DNA binding.
The band in 10q24 can be involved in different types of rearrangement such as cryptic deletion or translocation t(10;14). The common consequence is a truncated protein which retains the DNA binding domain but lack the Ankyrin domain (Migliazza et al., 1994). These rearrangements result in a constitutive activation of P52 which lead to the activation of the non-canonical NFKB pathway and thus promote B-cell malignancies (de silva, 2017; Guo, 2017).
