What Is Thalassemia?
Thalassemia is actually a group of inherited diseases of the
blood that affect a person's ability to produce hemoglobin,
resulting in anemia.
Hemoglobin is a protein in red blood cells that carries
oxygen and nutrients to cells in the body. About 100,000 babies
worldwide are born with severe forms of thalassemia each
year.
Thalassemia occurs most frequently in people of Italian,
Greek, Middle Eastern, Southern Asian and African Ancestry.
The two main types of thalassemia are called "alpha" and
"beta," depending on which part of an oxygen-carrying protein
in the red blood cells is lacking. Both types of thalassemia
are inherited in the same manner.
The disease is passed to children by parents who carry the
mutated thalassemia gene. A child who inherits one mutated gene
is a carrier, which is sometimes called "thalassemia trait."
Most carriers lead completely normal, healthy lives.
