    Sickle cell disease is the commonest inherited haemoglobinopathy in Britain and affects over 9000 people.1 Clinical severity varies considerably, but patients with the most severe disease have a life expectancy of just over 40 years. Conventional management of the disease is largely supportive, highlighting a pressing need for approaches that can alter the course of the disease. Trials in America have suggested that hydroxyurea can have a significant impact on the course of the disease, but in Britain it is proving virtually impossible to recruit patients into trials to confirm these results in a British population.

    The fact that the clinical severity of the sickle cell disease varies even within groups of patients with the same β globin genotype2 has led to the concept that the disease is a multigene disorder, with inheritance of α thalassemia and genes controlling the concentration of fetal haemoglobin, among others, modulating disease expression. …
