WebWhat is alpha thalassemia? Thalassemia (thal-uh-SEE-mee-uh) is a blood disorder that is inherited. This means it is passed down from one or both parents through their genes. When you have thalassemia, your body makes less hemoglobin than normal. Hemoglobin is an iron-rich protein in red blood cells. It carries oxygen to all parts of the body. WebBecause alpha thalassemia is inherited, family history and ancestry can help diagnose this blood disorder. A parent with alpha globin-making genes that are altered or missing, may have a child with a form of alpha thalassemia. Each child has a 25 percent chance of inheriting one, two or three missing genes.
