Noorian, Shahab; Sayarifard, Fatemeh; Farhadi, Elham; Barbetti, Fabrizio & Rezaei, Nima
Background: Maturity onset diabetes of the young type 2 (MODY) is an inherited disorder due to mutations
in glucokinase (GCK) gene, which lead to mild fasting hyperglycemia.
Case Presentation: Herein an otherwise healthy 9-year old boy with hyperglycemia is presented in whom the
diagnosis of MODY2 was suspected. Genetic studies showed heterozygous inactivating GCK gene mutation in
exon 8 (c.1010delA) in this patient. The same mutation was found in his father as well. The patient received
some dietary advices without any medication.
Conclusion: The identification of GCK mutation and diagnosis of MODY2 helps the clinicians to predict the
disease course, prognosis and to exclude other types of diabetes.
