Insulin secretion rates during graded intravenous glucose infusions administered to 6 MODY-2 subjects with glucokinase (GCK) mutations and 6 control subjects after an overnight fast (baseline) and a 42-h intravenous infusion of glucose (postglucose) at a rate of 4 to 6 mg · kg−1 · min−1. Administration of the glucose infusion enhanced the insulin secretory response to glucose in both control and glucokinase-deficient subjects. Data are expressed as means ± SE.
