From Fairfax, Virginia, USA:

My husband, who is 25, has type 1 diabetes (onset was at 12 years of age). What are the chances of our children having diabetes?


Assuming that your husband has Type 1A (autoimmune) diabetes, by far the commonest form in a 12 year old Caucasian in North America, the chances of any of your children having the same problem is about 7%. It would be rather smaller if you were the diabetic.


Additional comments from Dr. Brink:

Current research suggests about a 3-6% risk for children of males and about 2-4% risk for children of females. There is a national US study of potential diabetes in family members called DPT-1 that is ongoing. You should talk to your husband's diabetes doctor since he would know how to contact the nearest DPT-1 testing center if you would like more specific testing done free of charge as part of the DPT-1 study.


[Editor's comment: A number to call to get more information about the DPT is 1-800-425-8361. WWQ]
