This condition is caused ...Thalassemia is an inherited blood disorder. It is passed down from one or both parents through their genes. Learn about the4 types of alpha thalassemia, symptoms, treatment options, and more. Alpha thalassemia is a blood disorder that reduces the production of normal hemoglobin, the protein in red blood cells that carries oxygen to cells throughout the body. There are four types of alpha thalassemia, hemoglobin Bart hydrops fetalis syndrome or Hb Bart syndrome (the more severe form), HbH disease, silent carrier state and trait.Alpha-thalassemia is particularly common among certain populations of Southeast Asian descent. There is also a high number of carriers in Sub-Saharan Africa and Western Pacific regions.A carrier is a person who inherits one normal copy of a gene and one changed copy of a gene. Carriers of sickle cell disease are said to have "sickle cell trait.". People with sickle cell trait do not show signs of the disorder, but they could pass the gene to their children. They often do not know that they have the disorder until they are ...The alpha thalassemia (α-thalassemia) syndromes are a group of hereditary anemias of varying clinical severity.

The alpha thalassemias can be generally categorized as: Silent Carrier, Alpha Thalassemia Trait, Hemoglobin H disease, Hemoglobin H-Constant Spring, and Alpha Thalassemia major. Frequently, the diagnosis of alpha thalassemia trait in a parent is discovered after the birth of an affected child. Alpha-thalassemia (also called HbH disease) is caused by a loss of 3 alpha-globin genes (a-/-). This disease results in anemia, an enlarged spleen, and mild jaundice. Most individuals are mildly disabled by this condition. Some people with more severe disease require frequent blood transfusions.Thalassemia is an inherited (i.e., passed from parents to children through genes) blood disorder caused when the body doesn’t make enough of a protein called hemoglobin, an important part of red blood cells.

Clinical and laboratory features of the alpha-thalassemia syndromes. In: Steinberg M, Forget B, Higgs DR, et al., eds. Disorders of hemoglobin.The hemoglobin protein affected in alpha thalassemia is the alpha globin. People who inherit hemoglobin genes that are altered or missing from one parent but inherit normal genes from the other parent are called carriers. Carriers of alpha thalassemia usually have no signs or symptoms. However, they can pass the faulty genes on to their children.Alpha thalassemia: There are two genes (one from each parent) that produce alpha globin chains. Alpha thalassemia trait occurs if one or two of the four genes are affected. ... It is estimated that there are 35 million carriers of Thalassemia i.e. 1 in every 25 Indians.

This condition is caused ...The routine CBC is, therefore, a quick and inexpensive test that can be used as a universal screen for alpha thalassemia. An MCV of less than 80 fL or MCH less than 27 pg/cells in the absence of iron deficiency suggests the patient may be a carrier of alpha- or beta-thalassemia [1]. Background/objective: Alpha-thalassemia is one of the most prevalent genetic diseases, with the -α3.7 deletion being the most common mutation. Molecular studies have suggested mechanisms to explain the mild phenotype of "silent carrier" heterozygotes. However, the correlation between the clinical laboratory picture and the -α3.7 heterozygous state remains unclear, thus we chose to investigate.Alpha thalassemia: Missing or mutated genes related to the alpha globin protein. Beta thalassemia (also called Cooley anemia): Gene defects that affect production of beta globin protein. Inheriting the gene from both parents is called thalassemia major.
