Gene Replacement Therapy for Barth Syndrome

Gene Replacement Therapy for Barth Syndrome

Why is Barth syndrome an ideal target for a gene therapy?

Barth syndrome happens when there is something wrong with the tafazzin gene. When a disease is driven or caused by a single gene it is described as a monogenic disease and is an ideal indication for gene therapy – whose goal is to therapeutically deliver a working copy of the gene into an affected individual.


How does gene therapy work?

In gene therapy for Barth syndrome, the goal is to deliver a new, working copy of tafazzin to prevent and reverse the impact of Barth syndrome on the heart and skeletal muscles. This can be achieved in many ways, with possible different “packages” and “addresses” to deliver the working copy of the tafazzin gene.
