The molecular basis for familial persistent hyperinsulinemic hypoglycemia of infancy

Proc Assoc Am Physicians. 1996 Jan;108(1):14-9.


Familial persistent hyperinsulinemic hypoglycemia of infancy (PHHI) is a glucose metabolism disorder in neonates characterized by inappropriate insulin secretion in the presence of profound hypoglycemia. Loss of function mutations in the sulfonylurea receptor (SUR) gene recently have been implicated as a cause for familial PHHI in nine independent families. This review will describe the combined positional cloning and candidate gene strategy used to identify the SUR gene as the one responsible for PHHI. Potential roles for SUR in other disorders of insulin secretion remains to be determined.
