Impact of Type 2 diabetes on Glucokinase diabetes (GCK-MODY) phenotype in a Roma (Gypsy) family – case report

We found coincidence between the GCK-diabetes and T2D in the members of a single Roma (Gypsy) family. Since the chronic complications are rare in the GCK-diabetes, the major risk factor for the further morbidity may be in the development of the T2D. The overlapping of the GCK-diabetes with other types of diabetes, particularly the T2D, makes the diagnostics difficult and therefore, it might be one of the reasons why the estimated prevalence of the GCK-diabetes seems to be higher than the real one as it has been reported in several studies.
