A silent composite hemoglobinopathy characterized by gene sequencing.

Abstract

We report the case of a 35-year-old Tunisian women with a chronic anemia non investigated for a long time. Laboratory analysis using advanced technology of DNA sequencing revealed a compound heterozygote for Hb O Arab and cd 39 beta degrees-thalassemia. It's the first time that such a genotype has been characterized by gene sequencing.
