Features of maturity onset diabetes of the young that can assist with differential diagnosis

Young age at onset (usually but not exclusively < 25 years)

Usually non-obese, normotensive and without elevated lipid levels

Clear pattern of inheritance—diabetes present in at least three generations of family, and usually in parents and siblings

Autoantibodies to pancreatic islet cells almost always absent

Insulin reserve evident for some years after diagnosis

Glycosuria at lower than usual blood glucose levels (MODY1, 3 and 5)

Marked sensitivity for sulfonylureas (MODY1, 3 and 5)
