Is beta thalassemia trait serious?

People with beta thalassemia trait also can have a child with beta thalassemia disease. Beta thalassemia disease is not a form of sickle cell disease, but it is a serious lifelong illness.

What is the difference between thalassemia and beta thalassemia?

When thalassemia is called “alpha” or “beta,” this refers to the part of hemoglobin that isn't being made. If either the alpha or beta part is not made, there aren't enough building blocks to make normal amounts of hemoglobin. Low alpha is called alpha thalassemia. Low beta is called beta thalassemia.

Can thalassemia be cured?

Stem cell or bone marrow transplants are the only cure for thalassaemia, but they're not done very often because of the significant risks involved. Stem cells are produced in bone marrow, the spongy tissue found in the centre of some bones, and have the ability to develop into different types of blood cells.

Is beta thalassemia inherited?

People with this form are also at risk for iron overload. Beta-thalassemia is caused by genetic changes in the HBB gene and is typically inherited in an autosomal recessive manner. This means that people with thalassemia major or thalassemia intermedia have a genetic change in both of their copies of the HBB gene.

How do you get thalassemia?

Thalassemia occurs when there's an abnormality or mutation in one of the genes involved in hemoglobin production. You inherit this genetic abnormality from your parents. If only one of your parents is a carrier for thalassemia, you may develop a form of the disease known as thalassemia minor.

How is beta thalassemia diagnosed?

The diagnosis of β-thalassemia relies on measuring red blood cell indices that reveal microcytic hypochromic anemia, nucleated red blood cells on peripheral blood smear, hemoglobin analysis that reveals decreased amounts of HbA and increased amounts of hemoglobin F (HbF) after age 12 months, and the clinical severity ...

Is beta thalassemia the same as sickle cell?

While beta thalassemia is caused by a defect in the beta-globin gene, controlling the production of the beta-globin chains of hemoglobin, sickle cell disease is caused by a defect in hemoglobin itself with the presence of abnormal hemoglobin S.
