MODY 2 diabetes: an unusual presentation of diabetes

Diabetes mellitus includes a heterogeneous mix of metabolic diseases characterized by chronic hyperglycemia. The most common varieties of diabetes mellitus are Type 1 and Type 2, but there are other types. MODY diabetes (Maturity Onset Diabetes of the Young) is a clinically heterogeneous disease characterized by non-dependent insulin diabetes diagnosed early with dominant autosomal transmission and absence of auto-antibodies. It is the most frequent form of monogenic diabetes. Many patients are misclassified as Type 1 or Type 2 diabetes. In this paper, we are describing the case of a 51 year old male patient diagnosed with MODY 2 diabetes. The primary care physician should be aware of the existence of other types of Diabetes Mellitus different from the more common diabetes type 1 and type 2, and the importance of other cardiovascular risk factors such as hypercholesterolemia, hypertension or smoking.
