21‐Year‐Old Pregnant Woman with MODY‐5 Diabetes

Abstract

The term “Maturity‐Onset Diabetes of the Young” (MODY) was first described in 1976 and is currently referred to as monogenic diabetes. There are 14 known entities accounting for 1‐2% of diabetes and they are frequently misdiagnosed as either type 1 or type 2 diabetes. MODY‐5 is an entity of monogenic diabetes that is associated with genitourinary malformations and should be considered by obstetricians in pregnant women with a screen positive for diabetes, genitourinary malformations, and fetal renal anomalies. Correct diagnosis of monogenic diabetes has implications on managing patients and their families. We are reporting a case of a 21‐year‐old pregnant woman with a bicornuate uterus, fetal renal anomalies, and a family history of diabetes that were suggestive of a MODY‐5 diabetes.
