Alpha and Beta Thalassemia, What in the world?

So, what in the world is Alpha and Beta Thalassemia? Well, because I've heard this from five million doctors, just kidding only five but yeah its alot, I think I'm able to explain it. So here I go...
Alpha and Beta's are two important protein chains of the haemoglobin.

Alpha Thalassemia
In a normal healthy human, everyone receives four alpha globin genes. In alpha Thalassemia, the person affected only has two to three normal alpha globin genes for haemoglobin.
Alpha is a very important gene, because without it you would DIE! A person without any alpha globin gene have a condition called 'Bart's hydrops fetalis' and the baby will die during the pregnancy or shortly after birth. Another condition is Haemoglobin H disease which the person only recieves one alpha globin gene.

Beta Thalassemia
In a normal person, only two beta globin genes are given. Beta Thalassemia is a condition where one in two beta globin genes are mutated. For a patient, like me, who has beta thalassemia major will need regular blood transfusions from three to four weeks to correct the anaemia and accumulate the excess iron.
