A child whose mother has type 1 diabetes
has a 3% risk of developing the disease and a 6% risk if the child's father has it. The risk in siblings is related to the number of HLA
haplotypes that the sibling shares with the diabetic proband. If one haplotype is shared, the risk is 6% and if two haplotypes are shared, the risk increases to 12–25%.
From the above statistics, it is obvious that there are chances that there are high chances of progney suffering from diabetes if parents are suffering from diabetes.
