Maturity-Onset Diabetes of the Young (MODY)

Maturity-onset diabetes of the young (MODY) is a monogenic form of diabetes mellitus that follows an autosomal dominant pattern of inheritance and typically presents before the age of 25 years. MODY accounts for approximately 1-2% of diabetes mellitus and can be difficult to differentiate from the more common forms of diabetes. Differentiating factors include lack of autoantibodies usually observed with type 1 diabetes and lack of obesity often observed with type 2 diabetes. However, establishing an accurate diagnosis and identifying its genetic etiology allow for appropriate individualized management of symptoms and provide predictive and prognostic information for family members.
