Chromosome 18: BCL2 oncogene, Matt Ridley

Description:
Interviewee: Matt Ridley. The gene BCL2 is associated with the development of certain forms of leukemia that affect B-cells. If the gene is swapped onto a different chromosome, its protein is over-produced, resulting in B cells that do not function or self-destruct as they should.

Transcript:
On chromosome 18, there's an oncogene called BCL2. An oncogene is a gene involved in cancer. In people with a certain kind of leukemia, this gene has been moved in its entirety from chromosome 18 to chromosome 14. This is a gross rearrangement of the chromosomes that is one kind of mutation. Once the gene is on chromosome 14, it's more active. That means the overproduction of a certain kind of white cell, which leads to the leukemia.
