Monday 31 January 2005


Rearrangements of the MALT1 gene by the t(11;18)(q21;q21) and t(14;18)(q32;q21) are the most frequent structural chromosomal abnormalities in MALT lymphomas. These translocations lead to fusions of BIRC3/MALT1 and IGH/MALT1 respectively, and activate the NF-kappaB pathway.

- BIRC3/MALT1 fusion gene by t(11;18)(q21;q21) translocation in low-grade marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALToma)

- IGH-MALT1 by t(14;18)(q32;q21) in extranodal diffuse large B-cell lymphoma

- MALT1/MAP4 gene fusion occurs in diffuse large B-cell lymphoma (16804917)
