Introduction
Gestational diabetes is one of the most common medical disorders and may cause numerous of maternal and foetal complications, such as: preterm births, congenital defects, hypertrophic cardiomyopathy, metabolic changes, and macrosomia in neonates. One of the types of diabetes that may clinically manifest in pregnancy is GCK-MODY, caused by mutations in the glucokinase (GCK) gene.

Aim of the study
The aim of the study was to assess the impact of diabetes during pregnancy in women with GCK-MODY on their children’s health outcome and to determine the clinical and biochemical characteristics of children delivered by patients with GCK-MODY.

Material and methods
Study was multicentre, involving 50 children from paediatric diabetology departments in Gdansk, Katowice, Bialystok, and Lodz. The risk of GCK-MODY was evaluated on the basis of the medical history of the patient, the clinical course of the disease, and laboratory tests performed during diagnostic procedures. Data concerning family history, mothers’ health status, course of pregnancy, and perinatal period was collected.

Results
The study showed that among children with glucokinase mutation, born by mothers affected with GCK-MODY, 62% received 10 points in Apgar score in the first minute of life, whereas 92% (n = 46) obtained 10 points in Apgar score in the fifth minute of life. The average age of diagnosis of GCK-MODY in children was 8.25 ±4.76 years, and the average HbA1c during diagnosis was 6.43 ±0.71%. Statis-tically significant difference between the absence of macrosomia (birth weight > 91st percentile) in children with GCK-MODY diabetes in comparison to the general paediatric population (p = 0.0229) was observed.

Conclusion
According to the presented study, possible consequences of GCK-MODY during pregnancy on foetal development are generally less severe and may differ from those characteristic for other types of diabetes. Children born by mothers with diabetes should be followed up regarding glucose disorders. Further investigation of particular phenotypes of GCK-MODY, depending on the type of inherited mu-tation in mothers and their children, is required.
