Clinics and Pathology

Disease T-cell lymphoma of the small intestine of low grade malignancy
Phenotype / cell stem origin CD3, CD4, TCR A-B phenotype.
Epidemiology Only 1 case to date, a 28-year-old male patient.


Cytogenetics Morphological Sole anomaly.

Genes involved and Proteins

Gene NameIL2 (interleukin 2)
Location 4q27
Dna / Rna 6 exons
Protein Role in mediation of the immune system; member of the IL2 family of cytokines; binds to and signals through a receptor complex consisting of IL2Ralpha, IL2Rbeta, and gamma chain; T-cell growth factor.
Gene NameTNFRSF17 (tumor necrosis factor receptor superfamily, member 17)
Location 16p13.13
Dna / Rna 3 exons
Protein Role in mediation of the immune system; member of the TNF-receptor superfamily; binds to TNFSF13B/BAFF/BLys and TNFSF13/APRIL; promotes B-cell survival.

Result of the chromosomal anomaly

Hybrid gene
Description 5' IL2 - 3' TNFRSF17; breakpoint in intron 3 of IL2.
