Clinics and Pathology

Disease B cell non Hodgkin lymphoma (NHL)
Epidemiology Only 3 cases so far
Clinics The 3 patients had diffuse large B cell lymphoma (DLBCL); 2 of 2 patients were male patients, one presented with a history of follicular small cleaved cell lymphoma 15 yrs ago, when aged 47 yr. This patient died 6 mths later of progressive disease.

Cytogenetics

Additional anomalies 2 out of 2 cases had a t(14;18)(q32;q21) and both patients presented with MAKA (major karyotypic anomalies)

Genes involved and Proteins

Gene NameBCL6 (B-Cell Lymphoma 6)
Location 3q27.3
Dna / Rna spans on 25 kb;. 11 exons
Protein Sequence-specific DNA binding transcriptional repressor
Gene NameCIITA (MHC class II transactivator)
Location 16p13.13
Protein Non-DNA-binding transcriptional coactivator; transactivator of the major histocompatibility complex (MHC) class II genes

Result of the chromosomal anomaly

Hybrid gene
Description 5'-MHC2TA/BCL6-3' fusion transcripts but also the 5'-BCL6/MHC2TA-3' fusion transcripts,
  

To be noted

Additional cases are needed to delineate the epidemiology of this rare entity:
