Abstract EN
We report on a boy with diabetes mellitus and a phenotype indicating glucokinase (GCK) insufficiency, but a normal GCK gene examination applying direct gene sequencing.
The boy was referred for diabetes mellitus at 7.5 years old.
His father, grandfather and great grandfather suffered type 2 DM.
Several blood glucose profiles showed (BG) of 6.5–10 mmol/L L.
After three years on neutral insulin Hagedorn (NPH) in a dose of 0.3 IU/kg/day haemoglobin A1c (HbA1c) was 6.8%.
Treatment was changed to sulphonylurea 750 mg a day, and after 4 years HbA1c was 7%.
At that time a multiplex ligation-dependent amplification gene dosage assay (MLPA) was done, revealing a whole GCK gene deletion.
Medical treatment was ceased, and after one year HbA1c was 6.8%.
This case underscores the importance of a MLPA examination if the phenotype of a patient is strongly indicative of GCK insufficiency and no mutation is identified using direct sequencing.
