Insulin promoter factor 1

The gene encodes a transcription activator for several genes involved in development and function of the endocrine pancreas. Mutations cause autosomal dominant diabetes MODY4. Pancreatic agenesis 1 with exocrine and endocrine pancreatic secretion and permanent neonatal diabetes mellitus is an autosomal recessive disorder.
