Abstract
Permanent neonatal diabetes mellitus is a rare disorder known to be caused by activating mutations in KCNJ11 or ABCC8, inactivating mutations in INS, or very rarely in GCK or insulin promotor factor‐1 (IPF‐1) genes. We report a patient with permanent neonatal diabetes mellitus and severe exocrine pancreatic insufficiency. Ultrasound examination revealed pancreatic agenesis with a suggestion of a small amount of tissue in the head of the pancreas. Genetic testing revealed that the neonate had a homozygous Pro63fsX60 IPF‐1 mutation. This is the second reported case of neonatal diabetes mellitus secondary to a homozygous mutation in the IPF‐1 gene and supports the previously proposed biological role of IPF‐1 in the pancreatic development in human.Keywords
