title: Persistent hyperinsulinemic hypoglycemia of infancy.
abstract: In persistent hyperinsulinemic hypoglycemia (PHHI) of infancy, secretion of insulin is unregulated, resulting in profound hypoglycemia. Two histopathologic forms are known: focal adenomatous islet-cell hyperplasia and diffuse abnormalities of beta-cell hyperfunction. PHHI is caused by mutations in SUR1, which is a member of the ATP-binding cassette superfamily, and in Kir6.2, which is a member of the inwardly rectifying family of potassium channels.
