Novel Use of GLP-1 Receptor Agonist Therapy in HNF4A-MODY

Maturity-onset diabetes of the young (MODY) is an inherited form of diabetes caused by a mutation in a single gene. The frequency of mutation carriers for HNF4A-MODY has been reported to be 1.2% (1). Our group has previously published on the successful use of glucagon-like peptide 1 receptor agonist (GLP-1 RA) therapy in three consecutive generations of a family with an HNF1A-MODY (2). Although GLP-1 RA therapy has been studied in patients with HNF1A-MODY (3), it has not been studied in patients with HNF4A-MODY. In this father-son cohort, we demonstrate successful use of GLP-1 RA therapy in two patients with c.790:1 bp deletion of G; codon:264 mutations of HNF4A. The son first presented with neonatal hypoglycemia, then later developed diabetes and …
