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

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 name
BCL10 (B-cell CLL/lymphoma 10)
Location
1p22.3
Protein description
322 amino acids; contains a caspase recruitment domain; role in the apoptosis
Gene name
IGH (Immunoglobulin Heavy)
Location
14q32.33
