Web8 nov. 2024 · INTRODUCTION. The thalassemias are a group of hemoglobinopathies in which the normal ratio of alpha globin to beta globin production is disrupted due to a genetic variant in one or more alpha or beta globin genes. This abnormal alpha chain to beta chain ratio causes the unpaired chains to precipitate, leading to destruction of red blood cell ... Web13 nov. 2024 · INTRODUCTION. High-affinity hemoglobin (Hb) variants are a rare cause of congenital erythrocytosis. The first published case of a Hb variant associated with erythrocytosis was described in 1966 and designated Hb Chesapeake. 1 Since that time more than 200 high-affinity Hb variants have been identified. 2 The majority of patients …
