Hemoglobin E-beta thalassemia: factors affecting phenotype.

The phenotype of E-beta-thalassemia is affected by several genetic factors. The aim of this study was to analyze severity of E-beta-thalassemia and correlate with HbE, HbF, E/F ratios, beta-mutation and Xmn I polymorphism. Thirty cases of E-beta-thalassemia (23 with childhood onset) were studied. HbE levels were quantitated by HPLC. Xmn1 polymorphism and beta-mutations were studied by PCR-RFLP ...

Hemoglobin North Shore: a variant hemoglobin associated with the phenotype of beta-thalassemia.

Hemoglobin (Hb) North Shore (beta 134 val leads to glu) is a mutant hemoglobin that is associated with the phenotype of mild heterozygous beta-thalassemia. Heterozygotes are characterized low normal hemoglobin levels or mild anemia, microcytosis, increased HbA2, and 34%-38% Hb North Shore. The mechanism of the anemia and microcytosis associated with Hb North Shore was explored by studies of hem...

Hemoglobin Hope: a Beta Chain Variant.

Globin chain synthesis in the marrow and reticulocytes of beta thalassemia, hemoglobin H disease, and beta delta thalassemia.

a, fi, and ‘i globin chain synthesis in bone marrow and peripheral blood reticulocytes were studied in two patients with thalassemia major, two with thalassemia intermedia, one with thaIassemia minor, one with Hb H disease, and one with homozygous f38-thalassemia. Nine nonthalassemic patients served as controls. In thalassemia major, a marked imbalance of ato fichain synthesis was found in the ...
