Thalassemia Disorder Causes and Symptoms

Powerful Essays
Disorders passed from parents to children and inherited from generation to generation are called, “genetic disorders or diseases” (NIH, 2013). Thalassemia the focus of this paper is one such disorder. This disorder is linked to red blood cell abnormalities. A normal red blood cell delivers life-sustaining oxygen to every part of a human body, it also removes harmful gaseous waste product from the body by way of exhilaration. Hemoglobin, an iron-rich protein is a component of the red bloods cell which enable it perform its’ functions effectively (NIH, 2013).

What are Thalassemias?

Thalassemias are a group of blood disorders children inherit from their parents through genes. The body of a person with thalassemia will produce fewer red blood cells that are healthy with less hemoglobin than that of a person without this condition (National Heart, Lung, and Blood Institute, 2013). When a person’s body produces red blood cell below normal, or less hemoglobin, a condition called anemia develops. NIH (2013) further states that, people with gene disorder of Thalassemia can present with mild, moderate, or severe anemia.


Thalassemia occurs when genes that controls the way the body produce hemoglobin are absent or altered (NIH, 2013). The human body makes red blood cells, white blood cell, and platelets. As earlier mentioned, red blood cell contain hemoglobin. Hemoglobin’s carry two different types of protein chains: the alpha globin and beta globin. The body of a person with Thalassemia will not function well due to inadequate or abnormal production of alpha or beta protein chain which in turn, affects red blood cells performance of their functions.
