Clinics and Pathology

Disease the translocation is cytogenetically detectable in a minority of extranodal MALT lymphomas; irrespective of the presence of the 1;14 translocation, mutation or deletion of the BCL10 gene located at 1p22 can be detected by molecular genetic methods in 5-10% of extra-nodal MALT lymphomas, follicle centre cell lymphoma and diffuse large B-cell lymphoma; among MALT lymphoma a preferential association was noted with high-grade histology
Prognosis in MALT lymphoma there may be an association with aggressive histology and antibiotic-unresponsive forms


Cytogenetics Morphological the translocation is readily detectable by conventional karyotyping

Genes involved and Proteins

Note the breakpoints on chromosome 1p22 are located upstream of the promoter of the BCL10 gene, which shows inactivating mutations or deletions
Gene NameBCL10 (B-cell CLL/lymphoma 10)
Location 1p22.3
Protein 322 amino acids; contains a caspase recruitment domain; role in the apoptosis
Gene NameIGH (Immunoglobulin Heavy)
Location 14q32.33
