The Facts

  • The UK's National Health Service (NHS) has been cleared to use gene-editing therapy to treat the blood disorder beta thalassaemia.

  • The therapy, termed Casgevy, may help the estimated 2.3k people in the UK with thalassaemia, a rare group of inherited disorders in which the body produces too little hemoglobin, stunting its ability to carry oxygen.


The Spin

Narrative A

Gene-editing therapy will revolutionize thalassemia treatment with the UK’s approval of the groundbreaking Casgevy therapy. It corrects the faulty gene responsible for thalassemia, offering a potential lifelong cure. Previously, the only permanent solution was a bone marrow transplant, requiring a closely matched donor. Casgevy, instead, uses the patient’s own stem cells to produce healthy hemoglobin, drastically reducing the need for regular blood transfusions.

Narrative B

As CRISPR receives an outpouring of positive coverage due to its expected ability to cure diseases, it's important not to forget the negative side of the gene-editing industry. Gene-editing, if left unchecked, will undoubtedly go beyond fixing blood diseases and lead to a world where all differences among humans are artificially eradicated. We shouldn't allow the medical industry to play God when it comes to how we're born and how we develop.
