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.
