What is the probability that a child with two Type 1 diabetic parents will develop diabetes? Are there specific percentages pertaining to this matter?
The risk is approximately 30%. You can refer to The Risk of Developing I Diabetes for more information regarding the risk.
If Type 1 diabetes were purely "inherited," you would expect that the risk of diabetes in identical twins, or in the child of two parents with diabetes, would approach 100 percent. The fact that the risk is much lower is still not understood.
