Description
Congenital hyperinsulinism of infancy (CHI) is a rare heterogeneous disease mostly attributable to mutations in the genes encoding the KATP channel subunits found in pancreatic b-cells. Here, we report a child presenting at day 1 with persistent hyperinsulinemic hypoglycemia and who underwent open laparotomy and subtotal pancreatectomy with resection of tail and body of pancreas at 30 days of age. Normoglycemia was restored by Octreotide that was discontinued when the child was 7-month old. However, 3 months later Octreotide was re-administered as hypoglycemic attacks recurred. On follow-up, the child has adequate glycemic control and is thriving well with no neurodevelopmental morbidity. Genetic analysis revealed the novel mutation c.407G[A [p.R136H] in KCNJ11 encoding Kir6.2, confirming the diffuse form of CHI. This is to our knowledge the first reported Egyptian case of CHI due to a mutation in KCNJ11.
