Overview
Follicular lymphoma may be caused by a 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 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 may also be involved.[2]
