The GATA family zinc finger transcription factors GATA4 and GATA6 are known to play important roles in the development of the pancreas. In mice both Gata4 and Gata6 are required for pancreatic development. In humans GATA6 haploinsufficiency can cause pancreatic agenesis and heart defects. Congenital heart defects are also common in patients with GATA4 mutations and deletions but the role of GATA4 in the developing human pancreas is unproven.We report 5 patients with deletions (n=4) or mutations of the GATA4 gene who have diabetes and a variable exocrine phenotype. In four cases diabetes presented in the neonatal period (age at diagnosis 1-7 days). A de novo GATA4 missense mutation (p.N273K) was identified in a patient with complete absence of the pancreas confirmed at post mortem. This mutation affects a highly conserved residue located in the second zinc finger domain of the GATA4 protein. In vitro studies showed reduced DNA binding and transactivational activity of the mutant protein.We show that GATA4 mutations/deletions are a cause of neonatal or childhood-onset diabetes with or without exocrine insufficiency. These results confirm a role for GATA4 in normal development of the human pancreas.
