β thalassemia minor is caused by a β/β o or β/β + genotype. Only one of the two β globin alleles contains a mutation, so β chain production is not terribly compromised and patients may be relatively asymptomatic. Beta thalassemia most often occurs in people of Mediterranean origin. See more Thalassemias are inherited blood disorders characterized by decreased hemoglobin production. Symptoms depend on the type and can vary from none to severe. Often there is mild to severe anemia See more • Iron overload: People with thalassemia can get an overload of iron in their bodies, either from the disease itself or from frequent blood transfusions. Too much iron can result in … See more Both α- and β-thalassemias are often inherited in an autosomal recessive manner. Cases of dominantly inherited α- and β-thalassemias have been reported, the first of which was in an Irish family with two deletions of 4 and 11 bp in exon 3 interrupted by an … See more The American College of Obstetricians and Gynecologists recommends all people thinking of becoming pregnant be tested to see if they have thalassemia. Genetic counseling See more Normal human hemoglobins are tetrameric proteins composed of two pairs of globin chains, each of which contains one alpha-like (α-like) chain and one beta-like (β-like) chain. … See more Normally, the majority of adult hemoglobin (HbA) is composed of four protein chains, two α and two β-globin chains arranged into a See more Thalassemia can be diagnosed via a complete blood count, hemoglobin electrophoresis or high-performance liquid chromatography, and DNA testing.

Mutations in the alpha- and beta-globin genes lead to reduced or abolished globin-chain synthesis or cause structurally abnormal hemoglobin.

WebThalassemia is a blood disorder that leads to a decrease of hemoglobin production. Our bodies need hemoglobin because it helps red blood cells carry oxygen and low hemoglobin results in anemia.
