Gene editing frees a Coventry teenager from monthly transfusions
For Vian, 16, life no longer revolves around monthly blood transfusions. The Coventry teenager, born with thalassaemia, says she has energy to go out again after treatment using her own edited stem cells.
Thalassaemia affects haemoglobin, the protein that carries oxygen in red blood cells. Doctors collected Vian’s stem cells, edited them in a laboratory and returned them after chemotherapy last December. The changes increase production of foetal haemoglobin, helping overcome the blood disorder’s effects.

NICE explains why reducing transfusions matters: repeated transfusions can leave excess iron in vital organs, requiring treatment to remove it.
The procedure requires chemotherapy, and consultant Sarah Lawson describes the result as a “functional cure”: the underlying disease remains. Vian’s experience does not mean every patient will have the same outcome.
But her newly reported recovery has brought more freedom in everyday life. She has started studying health and social care at college and hopes to become a nurse, helping others as medical staff have helped her.
