Cytogenetic evolution of follicular lymphoma.
Follicular lymphoma (FL) is closely associated with the chromosomal translocation t(14;18)(q32;q21), which results in an overexpression of the anti-apoptotic bcl-2 gene product leading to a survival advantage of B-lymphocytes. However, in animal models, this genomic aberration is not sufficient for the initiation of the malignant phenotype. Additional genomic rearrangements are required for disease progression. In this review, the most important additional aberrations and possible candidate genes in the respective genomic regions are discussed. In addition, relevant data regarding their role in disease progression as well as the association with clinical presentation and clinical course are presented.
