Background: Congenital hyperinsulinism of infancy represents a group of heterogeneous disorders characterized by over-secretion of insulin from pancreatic β cells causing severe hypoglycemia. Genetically, congenital hyperinsulinism is caused by defects in key genes regulating insulin secretion (ABCC8, KCNJ11, GLUD1, GCK, HADH, SLC16A1, UCP2, HNF4A, and non-constantly HNF1A). The aim of our pr...

Background: Congenital Hyperinsulinism (CHI) is a heterogeneous genetically determined condition that is characterised by unregulated secretion of insulin from pancreatic β-cells. The most common and severe cases are caused by mutations in the ABCC8 gene encoding the SUR1 subunit of the KATP channel subunit. To assess the pathogenic effect of novel ABCC8 mutations we performed in-vitro functional studies.Objective and hy...
