Maturity‐onset diabetes of the young type 5 uncovered during pregnancy with a long‐term diagnosis of type 1 diabetes

Abstract

Abstract We report a case of missed diagnosis of maturity‐onset diabetes of the young type 5 uncovered during pregnancy with a previous diagnosis of type 1 diabetes. Maturity‐onset diabetes of the young type 5 cannot be excluded in early‐onset diabetes with positive islet‐related autoantibodies and type 1 diabetes‐prone human leukocyte antigen subtypes. Abdominal ultrasound should be used in all patients with pre‐gestational diabetes, and maturity‐onset diabetes of the young type 5 should be considered when renal abnormality is presented.
