How should I write about Progeria?

I may want to write a paper on progeria. I need to know what causes progeria? Is progeria preventable? I read some of the story on Zachary Moore the boy who had progeria. It's said that progeria speeds up life 30 times of normal life. Where can I find stories on progeria? How many people have had progeria? Where does progeria come from? Progeria is a strong serious disease.
