Patients with a genetic mutation that causes stable, mildly elevated blood glucose levels rarely develop typical diabetes-related complications, a new study finds.

The results, which may provide insight into the isolated role of glucose in the development of complications among patients with other types of diabetes, were published in the January 14 issue of the Journal of the American Medical Association by Anna M. Steele, PhD, of the National Institute for Health Research, Exeter Medical School, United Kingdom, and colleagues.

Mutation in the GCK gene causes abnormalities in the action of glucokinase, which regulates the secretion of insulin from the pancreatic beta cells in response to blood glucose levels. As a result, higher glucose concentrations are required to trigger insulin release.
