A novel case of compound heterozygous congenital hyperinsulinism without high insulin levels
BACKGROUND Congenital hyperinsulinism leads to unregulated insulin secretion and hypoglycemia. Diagnosis can be difficult and genetic testing may be warranted. CASE This patient initially presented at 11 months with seizure activity secondary to severe hypoglycemia. Her diagnostic evaluation included genetic studies, which confirmed congenital hyperinsulinism. A novel combination of mutations...
متن کاملInsulin levels measured with an insulin-specific assay in patients with fasting hypoglycaemia related to endogenous hyperinsulinism.
OBJECTIVE The finding of insulin levels above a minimum threshold at the time of symptomatic hypoglycaemia is crucial in the diagnosis of endogenous hyperinsulinism. The aim of this study was to evaluate insulin levels at the time of hypoglycaemia with an insulin-specific assay in such patients. DESIGN AND METHODS We measured insulin levels in 15 patients with fasting hypoglycaemia related to...
متن کاملMechanisms of amino acid-stimulated insulin secretion in congenital hyperinsulinism.
The role of amino acids in the regulation of insulin secretion in pancreatic beta-cells is highlighted in three forms of congenital hyperinsulinism (HI), namely gain-of-function mutations of glutamate dehydrogenase (GDH), loss-of-function mutations of ATP-dependent potassium channels, and a deficiency of short-chain 3-hydroxyacyl-CoA dehydrogenase. Studies on disease mouse models of HI suggest ...
متن کامل[Congenital hyperinsulinism].
In the last five years, our knowledge about the heterogenous syndrome of congenital hyperinsulinism (HI) has expanded explosively. HI may be familiar or sporadic, mild or severe, transitory or persistent, and histologically focal or diffuse. At least 63 disease-causing mutations have been found in the genes for the beta cell's ATP-dependent potassium channel, whose elements are the sulphonylure...
متن کاملA Case Series: Congenital Hyperinsulinism
INTRODUCTION Congenital hyperinsulinism is a rare inherited disease caused by mutations in genes responsible for β-cell's function in glucose hemostasis leading to profound and recurrent hypoglycemia. The incidence of the disease is about 1 in 50000 newborns. Mutations in at least 8 genes have been reported to cause congenital hyperinsulinism. Mutations in ABCC8 gene are the most common cause o...
