A study of families affected by thalassaemia major demonstrated that before antenatal diagnosis became an option, premature curtailment of reproduction was the most common parental response to their understanding of the genetic implications of the diagnosis. Subsequently parents of younger patients used antenatal diagnosis to meet or almost meet their birth expectations. There was no evidence that antenatal diagnosis contributed to any process of ‘compensating’ for existing affected offspring.
