Sickle cell disease is a genetic condition in which red blood cells, which should be circular, adopt a crescent shape and are sticky and rigidALAMY

The first patients to receive gene-editing treatments for inherited blood diseases will enter the new year free of agonising symptoms.

The experiments suggest that altering DNA could treat sickle cell disease (SCD) and beta thalassemia, conditions both caused by faulty genes that hamper the bloods ability to carry oxygen.

The companies behind the trials said that a patient in the US with SCD had been well since July. A thalassemia patient in Germany had been free of symptoms for nine months. Previously she had 16 blood transfusions a year.

British patients could be offered similar experimental therapies next year. The treatment for both conditions involved a high-precision gene-editing tool called Crispr-Cas9. It was used to alter the DNA of some of the cells of Victoria
