I have told all my children that they cannot give blood or donate their organs d/t this. I just wanted to make sure that my info is correct. I should correct myself on the anemia. I am anemic but iron supplements will not help. I get very tired at times but it does not interfere with my daily living.

My understanding (such as it is) is that the blood cells die early. Meaning a normal blood cell lives for 120 days.
In thalassemia the blood cells never truly mature and therefore cannot carry a full amount of oxygenated blood.
Genetics is an intersting thing. Tay Sach is normally known as a "Jewish" disease. Tay Sachs is also seen in French Canadian's along in the St. Charles area.
Maple Syrup disease in seen in the Amish (most have the same genetic pool).
My personal opinion, is that these things happen when there is a small pool of genes. This has alot to do with lets say if your family was in a specific region of Germany for a long time.
Thalassemia is a problem in Greeks because many Greeks refuse to marry non Greeks. Period. They even refuse to marry someone who is 1/2 Greek. Thus, the pool is very limited.
