Ok, I am starting to freak out - who among you have close family members (or worse still children) who now have this disease?

I am so scared for my nearly 16 yo daughter who is a beautiful dancer (and an even more beautiful person) and a wonderful son who is a runner and is at University.

I am interested (and terrified - but I need to know) whether anyone else has inherited this - or passed it on. I can cope with this, but I don't know what I will do if they are affected.

Thanks

Lyn
