title: [Alpha-thalassemia in Tunisia: molecular bases of hemoglobinosis H].
abstract: We report the study by restriction mapping of alpha genes in a case of Hb H disease in Tunisia. The genotype is: -alpha/-alpha which by itself is not usually responsible for the HbH phenotype. We postulate that the two remaining alpha genes are dysfunctional, this is under study.
