Summaries for Alpha-Thalassemia

About this section
UniProtKB/Swiss-Prot : 76 Alpha-thalassemia: A form of thalassemia. Thalassemias are common monogenic diseases occurring mostly in Mediterranean and Southeast Asian populations. The hallmark of alpha-thalassemia is an imbalance in globin-chain production in the adult HbA molecule. The level of alpha chain production can range from none to very nearly normal levels. Deletion of both copies of each of the two alpha-globin genes causes alpha(0)- thalassemia, also known as homozygous alpha thalassemia. Due to the complete absence of alpha chains, the predominant fetal hemoglobin is a tetramer of gamma-chains (Bart hemoglobin) that has essentially no oxygen carrying capacity. This causes oxygen starvation in the fetal tissues leading to prenatal lethality or early neonatal death. The loss of two alpha genes results in mild alpha-thalassemia, also known as heterozygous alpha-thalassemia. Affected individuals have small red cells and a mild anemia (microcytosis). If three of the four alpha- globin genes are functional, individuals are completely asymptomatic. Some rare forms of alpha-thalassemia are due to point mutations (non- deletional alpha-thalassemia).

MalaCards based summary : Alpha-Thalassemia, also known as alpha thalassemia, is related to alpha-thalassemia/mental retardation syndrome, chromosome 16-related and alpha-thalassemia/mental retardation syndrome, x-linked, and has symptoms including angina pectoris, edema and chest pain. An important gene associated with Alpha-Thalassemia is HBA2 (Hemoglobin Subunit Alpha 2), and among its related pathways/superpathways are Glucose / Energy Metabolism and Malaria. The drugs Darbepoetin alfa and Hematinics have been mentioned in the context of this disorder. Affiliated tissues include skin, bone and heart, and related phenotypes are microcytic anemia and abnormal hemoglobin

Disease Ontology : 12 Alpha thalassemia is a thalassemia involving the genes HBA1and HBA2 hemoglobin genes.

Genetics Home Reference : 26 Alpha thalassemia is a blood disorder that reduces the production of hemoglobin. Hemoglobin is the protein in red blood cells that carries oxygen to cells throughout the body.

NIH Rare Diseases : 54 Alpha-thalassemia is a blood disorder that reduces the body's production of hemoglobin. Affected people have anemia, which can cause pale skin, weakness, fatigue, and more serious complications. Two types of alpha-thalassemia can cause health problems: the more severe type is known as Hb Bart syndrome; the milder form is called HbH disease. Hb Bart syndrome may be characterized by hydrops fetalis; severe anemia; hepatosplenomegaly; heart defects; and abnormalities of the urinary system or genitalia. Most babies with this condition are stillborn or die soon after birth. HbH disease may cause mild to moderate anemia; hepatosplenomegaly; jaundice; or bone changes. Alpha-thalassemia typically results from deletions involving the HBA1 and HBA2 genes. The inheritance is complex, and can be read about here. No treatment is effective for Hb Bart syndrome. For HbH disease, occasional red blood cell transfusions may be needed.
