MODY 2 is a form of maturity onset diabetes of the young.MODY 2 is due to any of several mutations in the GCK gene on chromosome 7 for glucokinase. Glucokinase serves as the glucose sensor for the beta cell. Normal glucokinase triggers insulin secretion as the glucose exceeds about 90 mg/dl (5 mM). These loss-of-function mutations result in a glucokinase molecule that is less sensitive or less responsive to rising levels of glucose.
