What is thalassemia?

Thalassemia is a group of hereditary conditions with quantitative hemoglobin deficiency. The body's failure to make globulin molecules will lead to a compensatory mechanism to make other less compatible globulin molecules. The different types of thalassemia are defined based on what type of globulin molecule is deficient. The severity of these conditions depends on the type of deficient globulin chain, the number of deficient globulins, and the severity of the underproduction. Mild disease may only present as mild anemia whereas severe deficiency may not be compatible with life.
