G6PC2

G6PC2 encodes a glucose-6-phosphatase-related protein expressed in pancreatic islet cells. Common variation is associated with differences in fasting glucose regulation; it is not the insulin receptor.

Glucose sensing in pancreatic cells

Glucose sensing in pancreatic cells

G6PC2 encodes a glucose-6-phosphatase-related protein expressed in pancreatic islet cells. Common variation is associated with differences in fasting glucose regulation; it is not the insulin receptor.

Putting the pieces together

Dr. Purser’s notes discuss chromium and vanadium in the broader blood-sugar conversation. That discussion should begin with actual fasting glucose, HbA1c and the person’s clinical context. A G6PC2 finding does not diagnose diabetes or establish a need for those supplements, and glucose-lowering medicines must be considered before adding support.

A question to bring to your visit

Do my glucose measurements show a problem, and what intervention has evidence for my situation?
