If you are related to a person with a MODY mutation, you can get a genetic test to see if you are at risk of developing MODY. The first step would be for your affected relative to get a genetic test for MODY. If a mutation is found in one of the MODY genes, the lab could test you for the same mutation. It's important to make sure the affected person in your family has a detectable mutation, because genetic testing is not always able to find a mutation. If you also have a risk for MODY, you can act to avoid obesity by eating a healthy diet and exercising. Avoiding obesity may not prevent MODY, but it can postpone the development of symptoms until later in life, and also has other positive health benefits.
