Haemoglobin E disease – http://id.who.int/icd/entity/1898135714
Haemoglobin E disease is characterised by the synthesis of an abnormal haemoglobin called haemoglobin E (HbE), instead of the normal haemoglobin A (HbA). Subjects heterozygous for HbE (AE) have an asymptomatic condition with no clinical relevance, except for the risk of transmitting E/beta thalassemia if the other parent carries beta thalassemia. The severity of these E/beta thalassemia forms is very variable, the clinical picture ranging from that of beta thalassemia minor through to thalassemia intermedia to thalassemia major. Subjects homozygous for HbE (EE) are asymptomatic.
