Overview
Follicular lymphoma may be caused by translocation between chromosome 14 and 18 that results in the overexpression of the bcl-2 gene.
Causes
A translocation between chromosome 14 and 18 results in the overexpression of the bcl-2 gene.[1] As the bcl-2 protein is normally involved in preventing apoptosis, cells with an overexpression of this protein are basically immortal. The bcl-2 gene is normally found on chromosome 18, and the translocation moves the gene near to the site of the immunoglobulin heavy chain enhancer element on chromosome 14.
Translocations of BCL6 at 3q27 can also be involved.[2]
