Beta thalassemia genes are more widespread -- found in Africa, the Middle East, India, Southeast Asia, and around the Mediterranean. Someone with only one of the beta genes will have beta thalassemia trait, a mild anemia in which the red cells are smaller than normal.
There are many types of anemia. â¢ Iron-deficiency anemia is caused by a shortage of iron in the body. Your bone marrow needs iron to make hemoglobin, which is a protein molecule in the red blood cells. Without enough iron, the body can't produce enough hemoglobin for your red blood cells. â¢ Vitamin-deficiency anemia occurs when your diet lacks enough folate, vitamin B12 and other key nutrients. The body needs folate and vitamin B12 to produce enough healthy red blood cells.
