The word<br />

thalassemia<br />

Ghaziani<br />

The name thalassemia derives<br />

from a combination of two Greek<br />

words: thalassa meaning the sea,<br />

i.e. the Mediterranean, <strong>and</strong> anaemia<br />

(“weak blood”). emia or -hemia also<br />

-aemia or -haemia<br />

means blood. Thomas Cooley, a pediatrician<br />

in the USA who first described the<br />

clinical characteristics of this disorder in<br />

patients of Italian origin in 1925.<br />

Genes<br />

We all inherit many of our characteristics<br />

through thegenes we take from our parents.<br />

For example, theshape of our nose, colour<br />

of our eyes <strong>and</strong> whether weare tall or short.<br />

Similarly we inherit our hemoglobin type<br />

through the genes we get from our parents.<br />

We get one hemoglobin gene from our<br />

mother <strong>and</strong> the other one from our father.<br />

What is thalassemia<br />

Thalassemia is a genetic condition affecting<br />

the redblood cells. More specifically, it is a<br />

disorder of the hemoglobin molecule inside<br />

the red blood cells. Thalassemia affects the<br />

production of normal hemoglobin - a key<br />

constituent of human red blood cells. It is<br />

an inherited genetic disease i.e. a disease<br />

that is passed from parents <strong>to</strong> children<br />

through the genes (genetic). It is not infectious<br />

<strong>and</strong> cannot be passed on from one<br />

individual <strong>to</strong> the other by personal or any<br />

other contact, or through blood, transfusion<br />

food or air. Hemoglobin is a chemical<br />

found in the red blood cells which carries<br />

oxygen from the lungs <strong>to</strong> all parts of the<br />

body. Thalassemia occurs when a person is<br />

unable <strong>to</strong> produce the required amount of<br />

hemoglobin.<br />

The Facts<br />

1. When both parents carry normal or<br />

“healthy” hemoglobin genes, the child<br />

will inherit two normal genes <strong>and</strong> will be<br />

normal.<br />

2. When one parent carries normal or<br />

“healthy” hemoglobin genes but other<br />
