Maturity Onset Diabetes of the Young (MODY)

Maturity Onset Diabetes of the Young (MODY) is an inherited form of diabetes mellitus. It is caused by a change in one of eleven genes. Up to 5% of all diabetes cases may be due to MODY. Just like other people with diabetes, people with MODY have trouble regulating their blood sugar levels. This disorder is more like type 1 diabetes than type 2, although it can be confused with either type. In type 1, the pancreas cannot make and release enough insulin. People with type 2 diabetes, on the other hand, usually make enough insulin, but their bodies cannot respond to it effectively (known as insulin resistance). Type 2 diabetes is usually associated with being overweight, but that is not true of type 1 diabetes or MODY. However, obesity does matter. An obese person with a MODY gene mutation may develop symptoms of diabetes sooner than someone of normal weight.
