ABSTRACT: Positive diagnosis of diabetes is currently easy, but typing diagnosis of diabetes still remains a challenge for every clinician. It is currently accepted that types of diabetes apart from T1D and T2D can expand and include several forms of diabetes mellitus; From gestational diabetes, to all forms of secondary diabetes mellitus due to medications, intercurrent disease but also infections, and finally monogenic diabetes, whose diagnosis is not always easy to establish. The aim is to reveal the difficulties that clinicians may face in the process of etiological diagnosis regarding the suspicion of this type of monogenic diabetes, through the study of 2 cases, in which MODY type diabetes was suspected. Today we recognize 17 different genetic mutations that can all lead to MODY diabetes, the most common mutation of which is GCK coding for the glucokinase, the real sensor of pancreatic Beta-cell. The truly stable glycemic profile, with an A1C ranging between 7% and 7.5%, confirmed with a TIR always above 70% and a good MAGE, but also the rarity of degenerative complications and pharmacological therapeutic abstention which can last for years, these would be the most striking clinical characteristics of a GCK MODY.
