Type 1 diabetes is an acquired condition and individuals with a first degree relative who has the condition are at an increased risk of establishing the condition. Details concerning the risk of acquiring type 1 diabetes are offered below:
Diabetes Type 1 Inheritance
• In men with type 1 diabetes, the risk of their child likewise establishing the condition is one in 17.
• In women with type 1 diabetes who have their baby prior to the age of 25, the risk of the child establishing the condition is one in 25. If she has her baby after the age of 25, the risk falls to 1 in 100.
• If both parents have type 1 diabetes, the risk of the condition establishing in offspring differs in between 1 in 4 and 1 in 10. The dangers are rather increased if among the parents developed type 1 diabetes before the age of 11.
• Around 1 in 7 individuals with type 1 diabetes experience a condition called type 2 polyglandular autoimmune syndrome and these individuals have parathyroid and adrenal gland conditions in addition to type 1 diabetes If one of the parents has type 2 polyglandular autoimmune syndrome, the risk that the child will inherit the condition, including type 1 diabetes, is 50%.

Genes associated with type 1 diabetes
Some genes have consistently been determined in people with type 1 diabetes. Amongst white people, examples of such genes include the HLA-DR3 or HLA-DR4 genes. Carrying these genes raises the risk that offspring will acquire type 1 diabetes. Children born with the HLADR3/4-DQ 8 genotype make up almost 50% of all children who develop type 1 diabetes before they are 5 years of age. Some studies on other ethnic groups have actually revealed that comparable risks are connected with the HLA-DR7 genotype amongst African Americans and with the HLA-DR9 gene amongst Japanese people.
Hereditary research studies have likewise situated HLA class II genes at 6p21 and nearly 40 non-HLA genes that are carefully associated with the inheritance of type 1 diabetes.
