Maturity onset diabetes of the young (MODY) is a rare genetic form of diabetes that typically develops in adolescence or early adulthood. Unlike type 1 and type 2 diabetes, MODY is caused by a mutation in a single gene and is usually inherited in an autosomal dominant pattern, meaning that a person only needs to inherit one copy of the mutated gene from one parent to develop the condition.
There are several different types of MODY, each caused by a different genetic mutation. The symptoms and severity of MODY can vary depending on the specific type, but in general, people with MODY experience symptoms similar to those of type 2 diabetes, such as increased thirst and urination, fatigue, and blurred vision.
MODY is often misdiagnosed as type 1 or type 2 diabetes, but genetic testing can help confirm the diagnosis. Treatment for MODY typically involves medications and lifestyle changes, similar to type 2 diabetes, but may be more targeted based on the specific genetic mutation involved.
Since MODY is a genetic disorder, it is important for family members of people with MODY to undergo genetic testing and counseling to determine their risk of developing the condition and to make informed decisions about their healthcare.
