Core Topics
Congenital Hyperinsulinism Is About More Than “Low Sugar”
CHI involves inappropriate insulin secretion that can cause hypoglycemia, especially in infants and children. Because severe hypoglycemia can be dangerous, diagnosis and management require medical professionals familiar with the condition.
Genetics
SUR1 / ABCC8
The ABCC8 gene encodes SUR1, a key component of ATP-sensitive potassium channels involved in insulin secretion.
