WebWhen 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.

WebWhat is beta 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. Web•Heme is synthesized in a complex series of steps involving enzymes in the mitochondrion and in the cytosol of the cell. •Two distinct globin chains (each with its individual heme molecule) combine to form hemoglobin. •One of the chains is designated alpha. •The second chain is called "non-alpha" (usually designated beta in normal adult hemoglobin.
