Diabetes mellitus type 2 state may occur; however, ketoacidosis is uncommon. Type 2 diabetes primarily occurs as a result of obesity and lack of exercise. Some people are more genetically at risk than others. Type 2 diabetes makes up about 90% of cases of diabetes, with the other 10% due primarily to diabetes mellitus type 1 and gestational diabetes. In diabetes mellitus type 1 there is a lower total level of insulin to control blood glucose, due to an autoimmune induced loss of insulin-producing beta cells in the pancreas. Diagnosis of diabetes is by blood tests such as fasting plasma glucose, oral glucose tolerance
Epigenetics of diabetes Type 2 the C677t mutation. This is not a spontaneous mutation; it is actually hereditary. While the mutation does not inactivate the gene, it greatly reduces the efficiency, thus impairing the formation of methionine. The lack of this amino acid prevents methylation from occurring, and as said above, hypomethylation leads to increased susceptibility to Type 2 Diabetes. Type 2 diabetes associated sequence polymorphisms have been identified in 30 linkage disequilibrium (LD) blocks across the human genome, but their effects only explain a minor fraction of the observed phenotypic diversity among individuals. Previously, in other studies it has been demonstrated that connections between
