Abstract
Hemoglobin E interacts with beta-thalassemia to produce a disorder of variable severity that is the most common form of symptomatic thalassemia in Southeast Asia. The beta E-globin gene acts as a mild thalassemia gene; there are low levels of beta E-messenger RNA (mRNA) in reticulocytes, and preliminary evidence had suggested that this might be due to instability of the beta E-mRNA. Analysis of beta E-mRNA levels in the nuclei and cytoplasm of bone marrow erythroblasts compared with reticulocytes has shown higher levels of beta E-mRNA in the former, providing direct evidence that this is the case.
