Comment:

Homozygous mutations in PDX1 lead to pancreatic agenesis resulting in permanent neonatal diabetes and exocrine pancreatic insufficiency. Heterozygous mutations lead to a variable defect in insulin secretion and diabetes (MODY4) (PMID:23869298).

Additional Information:

Molecular genetics OMIM Mutation in the PDX1 gene is a rare cause of MODY (Fajans et al., 2001). In a consanguineous family, originally reported by Wright et al. (1993), in which an infant with pancreatic agenesis (260370) was homozygous for a ...
