This heterogeneity depends on the fact that the alpha 2-globin gene produces 2-3 times alpha-globin chains than the alpha 1-gene and the single remaining alpha 1-like globin gene in the -alpha 3.7 chromosome has a compensatory increase in the alpha-globin chain output. alpha-Globin gene mapping of HbH disease patients may be useful for predicting the clinical outcome and to improve genetic counseling.

These data showed that factor(s) in the mouse erythroleukemia cell can genetically complement the alpha-globin gene defect in these preleukemia patients with acquired hemoglobin H disease and suggest that altered expression of a gene in trans to the alpha-globin gene may be responsible for the acquisition of hemoglobin H disease in these patients.

In a Chinese patient with nondeletion hemoglobin-H disease (- -/alpha alpha T) (both alpha-globin genes are present but not fully functional) a normal ratio was maintained between the levels of alpha 1- and alpha 2-globin mRNA, implying that mRNA production from both alpha-globin genes is suppressed in a balanced manner.
