Introduction: Congenital hyperinsulinism (HI) is the leading cause of persistent hypoglycemia in infants and children. It is a rare glucose metabolism disorder characterized by unregulated secretion of insulin that leads to hyperinsulinemic hypoglycemia (HH). Most cases are caused by mutations in the KATP-channel genes ABCC8 and KCNJ11. KATP-HI can be classified into two distinct histological forms: a diffuse form, in which all of the pancreatic β-cells a...

Introduction: Congenital hyperinsulinism (CHI) is a disorder of pancreatic beta-cells characterized by inappropriate secretion of insulin leading to hyperinsulinemic hypoglycemia. Insulin secretion is a complex, genetically regulated process. Mutations in several genes known to regulate insulin secretion result in CHI. Recently, non-coding mutations in HK1, which cause the aberrant expression of hexokinase 1 (HK1) in beta cells, have been reported as a novel c...
