Screening programmes must consider societal values

Most of the recent advances in medical genetics have been in basic science and technology. Experience of translating these into effective, population based interventions is limited, but the potential is great, especially for lower resource countries.1 2 This is well illustrated by the experience of the national thalassaemia screening programme in Iran (p 1134), a comprehensive, primary care based programme for screening and genetic counselling. Since the programme's inception in 1996 premarital screening of 2.7 million couples has been carried out over five years, followed by genetic counselling of more than 10 000 couples who were found to be positive. This has resulted in a 70% reduction in the expected annual birth rate of affected infants.3 For a vast, lower-resource country with a population of 68 million, this is a considerable achievement.
