Brief Summary: This is a single case report describing possible new candidate gene (ADCY7) for congenital hyperinsulinism. Mutations in the ADCY7 may be cause of hyperinsulinism but more cases are needed and molecular mechanisms studied detail.

Hypoglycemia in infants and children can lead to seizures, developmental delay, and permanent brain damage. Hyperinsulinism (HI) is the most common cause of both transient and permanent disorders of hypoglycemia. HI is characterized by dysregulated insulin secretion, which results in persistent mild to severe hypoglycemia. The various forms of HI represent a group of clinically, genetically, an...

Glucokinase hyperinsulinism is a rare variant of congenital hyperinsulinism caused by activating mutations in the glucokinase gene and has been reported so far to be a result of overactivity of glucokinase within the pancreatic beta-cell. Here we report on a new patient with difficulties to diagnose persistent hyperinsulinism and discuss diagnostic procedures of this as well as the other report...

N eonatal hyperinsulinism is the most important cause of hypoglycemia in infancy (1,2). The inappropriate oversecretion of insulin is responsible for profound hypoglycemia, requiring aggressive treatment to prevent brain damage (1–3). Neonatal hyperinsulinism is often resistant to medical therapy (1–4), and pancreatectomy is required for many sufferers (1,5–6). The histopathological lesions ass...

Persistent hypoglycaemia in infancy is most commonly caused by hyperinsulinism. A case is reported of the somatic loss of the maternal 11p in an insulin secreting focal adenoma in association with a germline SUR-1 mutation on the paternal allele in a baby boy with hyperinsulinism diagnosed at 49 days old. A reduction to homozygosity of an SUR-1 mutation is proposed as a critical part of the cau...

Congenital or monogenic hyperinsulinism (HI) is a group of rare genetic disorders characterized by dysregulated insulin secretion and the most common cause persistent hypoglycemia in children. Knowledge normal glucose homeostasis allows for better understanding underlying pathophysiology hyperinsulinemic hypoglycemia, facilitating timely diagnosis management. The goal management to prevent cere...

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...

Congenital hyperinsulinism (HI) is a clinically and genetically heterogeneous entity. The clinical heterogeneity is manifested by severity ranging from extremely severe, life threatening disease to very mild clinical symptoms, which may even be diYcult to identify. Furthermore, clinical responsiveness to medical and surgical management is extremely variable. Recent discoveries have begun to cla...

OBJECTIVE To describe the long-term metabolic outcome of children with congenital hyperinsulinism after near-total or partial elective pancreatectomy. RESEARCH DESIGN AND METHODS Patients (n = 105: 58 diffuse and 47 focal congenital hyperinsulinism) received operations between 1984 and 2006. Follow-up consisted of periodic measurements of pre- and postprandial plasma glucose over 24 h, OGTT, ...
