-
A rare congenital isolated hyperinsulinism disorder with characteristics of neonatal presentation of severe refractory hypoglycaemia in the first two days of life with limited response to medical management sometimes requiring pancreatic resection. Newborns are often large for gestational age with mild to moderate hepatomegaly and diffuse form of hyperinsulinism due to SUR1 deficiency. Persistent hypoglycaemia, hyperglycaemia and type 1 diabetes mellitus may develop later in life. Life-threatening hypoglycaemic coma or status epilepticus have also been associated. There is evidence the disease is caused by homozygous, compound heterozygous, or heterozygous mutation in the ABCC8 gene on chromosome 11p15.
