83 Malays with HbE beta-thalassaemia who were not transfusion dependent were investigated. 79 persons showed no beta0 formation indicating the predominant gene in Malays with HbE beta-thalassaemia was beta0. HbF assays showed levels that were similar to transfusion dependent patients. Further studies are necessary to determine the presence of the alpha, (alpha+) gene Interacting with HbE and beta0 to produce the milder phenotype of HbE beta-thalassaemla.
