You must be aware of diabetes and its types, such as type 1 and type 2 diabetes. However, have you ever wondered or heard about another type of diabetes known as Maturity Onset Diabetes of the Young (MODY)?
Yes, you read that right. It’s a relatively rare condition, unlike type 1 and type 2 diabetes. MODY is a form of diabetes that often goes undiagnosed or misdiagnosed and is caused by specific genetic mutations.
In this article, we will learn more about MODY, and explore how it differs from other forms of diabetes.

Now you might be wondering how MODY maturity-onset diabetes is caused. Let’s understand the causes.
Unlike Type 1 diabetes, which is an autoimmune disorder, MODY is not caused by the immune system attacking the insulin-producing cells in the pancreas. The clinical features of MODY are:
1. Early Age at Onset: People diagnosed with diabetes before the age of 25.
2. Familial History: Presence of diabetes across three or more generations, with at least one parent affected.
3. Familial History: Presence of family or personal history of autoimmunity.
4. Absence of Ketoacidosis: No history or evidence of ketoacidosis.
5. Lack of Obesity or Insulin Resistance Signs: People without obesity or indicators of insulin resistance, such as acanthosis nigricans.
6. No Blood Insulin Antibodies Detection: Absence of autoimmune response as seen in Type 1 diabetes, evidenced by the lack of insulin antibodies.
MODY comprises only 1–5% of all diabetes cases and 1–6% of pediatric cases. Due to its rarity, there’s a high chance of misdiagnosis, with about 90% of cases initially labeled as type 1 or type 2 diabetes.
Types of MODY and their genetic mutations
There are several different subtypes of MODY in diabetes which include MODY 1, MODY 2, MODY 3, MODY 4, MODY 5, and MODY 6, each with its distinct genetic mutation and clinical features.
Mutation in genes affects the glucose-sensing cells in the pancreas, resulting in elevated blood sugar levels.
NOTE: MODY 2 is the most common subtype and is caused by a mutation in the GCK gene.

Symptoms and diagnosis of MODY
The symptoms of MODY can vary depending on the specific subtype and the person. However, common symptoms include:
- Frequent urination
- Excessive thirst
- Unexplained weight loss
- Fatigue
MODY’s genetic basis, age of onset, and misdiagnosis history differentiate it from both Type 1 and Type 2 diabetes.
It is important to note that the symptoms of MODY can be similar to those of Type 2 diabetes, which can lead to misdiagnosis. To accurately diagnose MODY, genetic testing is necessary. This involves analyzing the DNA for specific mutations associated with MODY.
Diagnosis of MODY
The diagnosis involves considering the patient’s age, family history, and symptoms, followed by specific blood tests and genetic testing.
Genetic Testing for MODY
Genetic testing is essential for diagnosing MODY, helping determine the specific genetic mutation causing the condition. It involves assessing pancreatic antibodies and C-peptide levels.
Treatment and Management
Treatment depends upon confirmation of MODY and its subtypes so it is advisable to closely monitor and consult your Doctor for personalized treatment plan.
- Some people are able to manage their condition with lifestyle changes like diet and exercise.
- Doctors treat most forms of MODY with a type of oral diabetes drug called sulfonylureas.
- Depending on the type of MODY you have, you may need injections of insulin.
Here comes Fitterfly where we understand your concern and create a personalised plan exclusively for you. Through this program, you will get expert guidance and better lifestyle management so that you need to think again about how to manage your condition.
How is MODY different from Type 1 and Type 2 diabetes?
- If a young person is diagnosed with diabetes that looks like Type 1 but has unusual traits, it’s a good idea to do genetic testing to check for MODY.
- A genetic diagnostic test can determine if the person has MODY and, if so, specify the type of MODY involved.
- This approach ensures accurate diagnosis and personalized management for the individual’s unique diabetes profile.
