This study described the expression of ßE-globin in newborns heterozygous for HbE. Despite the lower level of HbE, the pattern of ßE-globin gene expression was similar to ßA-globin because the increase in HbE and HbA reached the peak level at the same time. A delayed decline of HbF was observed.

Key words: thalassemia, hemoglobin E, hemoglobin F, neonatal screening, globin gene expression.
