Alpha thalassemia is a blood disorder that reduces the production of hemoglobin, the protein in red blood cells that carries oxygen to cells throughout the body. There are two types of alpha thalassemia, hemoglobin Bart hydrops fetalis syndrome or Hb Bart syndrome (the more severe form) and HbH disease. Alpha thalassemia also occurs frequently in people from Mediterranean countries, North Africa, the Middle East, India, and Central Asia. Alpha thalassemia typically results from deletions involving the HBA1 and HBA2 genes. People who have alpha thalassemia trait can have mild anemia. However, many people with this type of thalassemia have no signs or symptoms. Treatments for thalassemias depend on the type and severity of the disorder.
