title: Homozygous G gamma delta beta thalassaemia.
abstract: This report describes the clinical and haematological findings in three siblings homozygous for G gamma delta beta thalassaemia in an Indian family. There was a mild to moderate anaemia and markedly abnormal red cell morphology. Haemoglobin analysis showed 100% Hb F, solely of the G gamma type, with a pancellular but uneven distribution. Considerable chain imbalance was detectable in globin synthesis studies. In contrast to five previously reported cases, these children were essentially asymptomatic and have never required transfusions.
