Siblings with Type 1

Mayo Clinic "The Essential Diabetic Book" (c) 2009 states:

relative / type 1 risk / type 2 risk

mother / 1-5% / 5-20%
father / 5-15% / 5-20%
both parents / 0-25% / 25-50%
brother/sister / 5-10% / 25-50%
identical twin / 25-50% / 60-75%

How ironic that I just read this excerpt in the book last night.

It's too difficult to put a % on since there are so many genes involved and when you start talking about 2 generations you are looking at so many different sources for the genes. Plus, since it's not understood why anyone gets diabetes it's very difficult to figure out your chances of getting it.

It is possible…it is called genetics. I don't know a % for it but do know from schooling that it is possible. At least this is what doctors have told me.
