Diabetes mellitus type 1 factors include having a family member with the condition. The underlying mechanism involves an autoimmune destruction of the insulin-producing beta cells in the pancreas. Diabetes is diagnosed by testing the level of sugar or glycated hemoglobin (HbA1C) in the blood. Type 1 diabetes can be distinguished from type 2 by testing for the presence of autoantibodies. There is no known way to prevent type 1 diabetes. Treatment with insulin is required for survival. Insulin therapy is usually given by injection just under the skin but can also be delivered by an insulin pump. A diabetic diet and exercise are important
Epigenetics of diabetes Type 2 associated FTO gene, which has shown to increase susceptibility to both obesity and Type 2 Diabetes. When looked at further, it was shown to have increased methylation levels in a haplotype associated with Type 2 Diabetes. To find exactly which portion of the gene led to the higher levels of risk, one group of researchers performed a sliding window analysis. Using the information, they narrowed the search down to the 46 kb linkage disequilibrium block, and within that region found a 7.7 kb region in which methylation levels were abnormally high. Pyrosequencing found that this difference was due to single
