GCK MODY

This episode delivers a precise analysis of GCK-MODY, also known as MODY2, a genetic form of diabetes caused by heterozygous inactivating mutations in the glucokinase gene. We explore how this molecular defect alters the pancreatic glucose sensor, shifting the glycemic threshold upward. Listeners will learn why patients exhibit lifelong, stable, mild fasting hyperglycemia that rarely progresses, why microvascular complications are exceptionally uncommon, and why pharmacological management is typically unnecessary outside of pregnancy.
