My dad had diabetes, as well as one brother. Interestingly, I have an aunt on my dad's side with RA that had a very high fever illness at about the same age that I had mine, and she told me she's wondered for years if I would develop some autoimmune condition and lo and behold - here I am.

I'm wondering about my mom and a very mild case of MG, which makes me wonder if mine isn't congential myasthenic syndrome. I may find out fairly soon. I'll post when I get more info on me. By the way, she also had an illness with very high fever when she was younger.
