It is suggested that the co-inheritance of hemoglobin SC disease and heterozygous alpha-thalassemia-2, probably by decreasing the tendency toward intracellular hemoglobin S polymerization, contributed to her prolonged survival and relatively mild clinical course....
Two alpha chains plus two beta chains constitute HbA, which in normal adult life comprises about 97% of the total hemoglobin; alpha chains combine with delta chains to constitute HbA-2, which with HbF (fetal hemoglobin) makes up the remaining 3% of adult hemoglobin. Alpha thalassemias result ...

alpha chains plus two beta chains constitute HbA, which in normal adult life comprises about 97% of the total hemoglobin; alpha chains combine with delta chains to constitute HbA-2, which with HbF (fetal hemoglobin) makes up the remaining 3% of adult hemoglobin. Alpha thalassemias result from...
D. Alpha thalassemia (α thalassemia) has two clinically significant forms: hemoglobin Barts hydrops fetalis (Hb Barts) syndrome and hemoglobin H (HbH) disease (see the table below). Hb Barts syndrome is the more severe form. Death usually occurs in the neonatal period. A 5-year-old patient...
Hemoglobin C–β thalassemia Individuals may be compound heterozygotes for beta thalassemia and hemoglobin C, which could result in mild to moderate chronic hemolytic anemia. These patients are more likely to be symptomatically anemic due to alpha chain/beta chain expression imbalance, though generally...

Hemoglobin Nigeria (a-81 Ser-e-Cys):A New Variant Associated With a-Thalassemia Hematologic and globin synthesis studies were performed in a black American family in which the genes for alpha-thalassemia and hemoglobins (Hb) S and C were segregating. The following distribution of these ...
Does cigarette smoking affect the diagnostic reliability of hemoglobin alpha 2 delta 2 (HbA2)? Quantitation of hemoglobin 22 (HbA2) is a basic and confirmatory test in diagnosing the carrier state of -thalassemia. The present study was designed to in... IS Tarazi,MM Sirdah,HE Jeadi,... ...
Alpha-thalassemia is of particular importance to neonatologists because its clinical manifestations are present in utero and at birth. The more severe forms of alpha-thalassemia are found in Southeast Asians (Glader and Look, 1996) andless commonly in infants of Mediterranean origin, and are rare...
