  Thalassemia - Wikipedia, the free encyclopedia
Thalassemia (American English) (or thalassaemia in British English), also known as "Cooley's anemia", is an inherited disease of the red blood cells, classified as a hemoglobinopathy.
Thalassemia Minor, although not life threatening on its own, can affect quality of life due to the effects of a mild to moderate anemia.
Reports of dominantly inherited α and β thalassemias have been reported the first of which was in an Irish family who had a two deletions of 4 and 11 bp in exon 3 interrupted by an insertion of 5 bp in the β-globin gene.

Thalassemia is an inherited disorder that affects the production of normal hemoglobin (a type of protein in red blood cells that carries oxygen to the tissues of the body).
Beta thalassemia is caused by mutations in the beta chain of the hemoglobin molecule.
Thalassemia major is inherited by an autosomal recessive gene, which means that two copies of the gene are necessary to produce the condition, one inherited from each of two carrier parents who have thalassemia minor.

 About Thalassemia
Since thalassemia is not a single disorder but a group of related disorders that affect the human body in similar ways, it is important to understand the differences between the various types of thalassemia.
As in mild alpha thalassemia, physicians often mistake the small red blood cells of the person with beta thalassemia minor as a sign of iron-deficiency anemia and incorrectly prescribe iron supplements.
While thalassemia patients were given infrequent transfusions in the past, clinical research led to a more frequent program of regular blood cell transfusions that has greatly improved the patients' quality of life.

 Thalassemias
Thalassemias is the name for the group of genetic blood diseases which vary widely in severity.
Thalassemia is a genetic disorder that involves the decreased and defective production of hemoglobin, a molecule that's found inside all red blood cells and is necessary to transport oxygen throughout the body.
Frequently, thalassemia is not diagnosed in a family until a baby is born with the disease.

Thalassemia is a group of genetic blood diseases that vary widely in severity involving decreased and defective production of hemoglobin, a molecule that's found inside all red blood cells and is necessary to transport oxygen throughout the body.
Both forms of thalassemia are genetic disorders and both parents have to pass the thalassemia gene to their child for him or her to have the disease.
However, genetic counseling is important for families that carry the thalassemia gene because someone with the trait has a 25% (1 in 4) chance of having a child with the disease if his or her partner also carries the trait.

 What Causes Thalassemia?
Thalassemia is caused by variant or missing genes that affect how the body makes hemoglobin.
A person who inherits a thalassemia gene or genes from one parent and normal genes from the other parent is a carrier (thalassemia trait).
If two people with alpha thalassemia trait (carriers) have a child, the baby could have a mild or severe form of alpha thalassemia or could be healthy.

 Thalassemia overview
Thalassemia is a difficult subject to explain, since the condition is not a single disorder, but a group of defects with similar clinical effects.
With alpha thalassemia, the "failed" genes are almost invariably lost from the cell due to a genetic accident.
The patient has thalassemia that is more severe than thalassemia trait, but not so severe as to require chronic transfusion as do the patients with thalassemia major.

 Pathology
The thalassemias are a diverse group of inherited disorders in which the rate of production of certain hemoglobins is decreased leading to an imbalance of globin chains available for hemoglobin dimer construction.
In a thalassemia, it is synthesis of the a chain that is defective.
In thalassemia minor, the severity of disease expression may only be seen as mild anemia and a microcytic state.

Persons with thalassemia minor have a 50/50 chance to pass the gene to their offspring, who would also have thalassemia minor if their other beta chain is normal.
Thalassemia major is inherited as an autosomal recessive disorder, which means that in order to have the condition, a person must inherit the defective gene from both parents, each of whom have thalassemia minor.
