MODY is a rare form of diabetes that is different from type 1 and type 2 diabetes. It is caused by a gene mutation and is passed down through families. Children who inherit the mutated gene from their parents usually develop symptoms before age 25.

Depending on the type of young-onset diabetes, there are different treatments. For example, MODY 2 diabetes can be managed with proper diet and regular exercise, while types 1, 3 and 4 are often prescribed sulfonylureas.
