    Hello,
         This is a common question, and I imagine if I had a family member with diabetes I would be worried too.  At present we can't accurately predict the likelihood of developing type 1 diabetes if you have a relative with it.  
         We know that some families tend to develop autoimmune diseases (like type 1 diabetes, thyroid disease and coeliac disease).  However other families don't have any common genetic tendencies. 
    If you follow the attached link you can find out more about an international study into the genetic causes of type 1 diabetes.  Maybe you can even be part of it!
