Patients and Methods: We analyzed the case of three brothers that we suspected as affected by Type 1 diabetes because of their low BMI without clinical or biochemical parameters for this diagnosis. Their father was diagnosed as affected from Type 2 diabetes at the age 31 years old. Results: Genetic analysis revealed the presence in all analyzed family members of non-sense Ser 383x GCK mutation mapping in exon 9 of the gene. Conclusions: We described a case of a patient misdiagnosed as T2DM. Only after the observation of a mild hyperglicemia also in his three sons, we supposed the diagnosis of MODY 2 and we confirmed it through the genetic test. These observations enforce the validity of the designed clinical algorithm for the identification of patients to be selected for the genetic diagnosis of MODY 2.展开更多
