1. Identity

ICD-Topo C420,C421,C424 BLOOD, BONE MARROW, & HEMATOPOIETIC SYS
Atlas_Id 1398

2. Clinics and Pathology

Disease Extra-nodal Marginal Zone B-cell lymphoma (MZBCL) of mucosa-associated lymphoid tissue (MALT) type, also called MALT lymphoma
Note MALT lymphomas without the t(3;14) are frequently associated with either a t(1;14)(p22;q32) ( BCL10 / IGH), a t(11;18)(q21;q21) ( API2 / MALT1, or a t(14;18)(q32;q21) (IGH/MALT1)
Epidemiology 9 cases detected to date
Clinics MALT lymphoma is an indolent disease involving most often the stomach, the lung, the thyroid, the salivary gland, the orbit, and the skin, with a non random anatomic distribution according to the translocation. The t(3;14) is frequently found in MALT lymphomas of the thyroid, the orbit, and the skin.

3. Cytogenetics

Additional anomalies +3 is found in half cases

4. Genes involved and Proteins

Gene NameFOXP1 (Forkhead box P1)
Location 3p13
Protein Transcription factor; member of the FOXP subfamily, characterized by a DNA binding forkhead.
Gene NameIGH (Immunoglobulin Heavy)
Location 14q32.33

5. Result of the chromosomal anomaly

Hybrid gene
Description Breakpoint upstream the first 5' non coding exon of FOXP1
  

6. To be noted
