Hemoglobin E (HbE) is an abnormal hemoglobin with a single point mutation in the β chain. At position 26 there is a change in the amino acid, from glutamic acid to lysine (E26K). Hemoglobin E is very common among people of Southeast Asian, Northeast Indian, Sri Lankan and Bangladeshi descent. [1] [2]
Beta thalassemias (β thalassemias) are a group of inherited blood disorders.They are forms of thalassemia caused by reduced or absent synthesis of the beta chains of hemoglobin that result in variable outcomes ranging from severe anemia to clinically asymptomatic individuals.
Hemoglobin S/ beta thalassemia: common in African and Mediterranean populations, it is clinically similar to sickle-cell anemia. [35] Delta-beta thalassemia is a rare form of thalassemia in which there is a reduced production of both the delta and beta globins. It is generally asymptomatic. [36] There are two clinically significant combinations ...
Hemoglobin E/ beta thalassemia: common in Cambodia, Thailand, and parts of India, it is clinically similar to β thalassemia major or β thalassemia intermedia. [60] Hemoglobin S/ beta thalassemia: common in African and Mediterranean populations, it is clinically similar to sickle-cell anemia. [61]
Thalassemia is an inherited condition that has variants in alpha or beta globin genes that result in lower levels of globin chains required to make hemoglobin, resulting in alpha thalassemia or beta thalassemia, respectively. [3] Diagnosis is made by DNA analysis for alpha thalassemia and hemoglobin analysis for beta thalassemia. [3]
Hemoglobin subunit beta (beta globin, β-globin, haemoglobin beta, hemoglobin beta) is a globin protein, coded for by the HBB gene, which along with alpha globin , makes up the most common form of haemoglobin in adult humans, hemoglobin A (HbA). [5] It is 147 amino acids long and has a molecular weight of 15,867 Da.
Beta-thalassemia is a genetic disease mostly caused by beta-globin gene mutations. [18] Clinical diagnosis is based on interpretation of the peripheral blood smear, which examines red blood cell morphology, followed by hemoglobin analysis and confirmed by DNA sequencing.
Patients with thalassemia gradually accumulate high levels of iron (Fe) in their bodies. This build-up of iron may be due to the disease itself, from irregular hemoglobin not properly incorporating adequate iron into its structure, or it may be due to the many blood transfusions received by the patient.
