What is MODY test?
What is MODY test?
Quest Diagnostics is the only large commercial lab that offers comprehensive DNA testing for monogenic diabetes, a form of diabetes that is often mistaken for type 1 or type 2. 1. The most common form of monogenic diabetes is maturity-onset diabetes of the young (MODY), which represents about 2% of all diabetes cases.
How much is genetic testing for MODY?
The cost of genetic testing was set at 2,580 USD per individual tested, reflecting the cost of simultaneously sequencing GCK, HNF1A, and HNF4A (Commercial Reference Laboratory pricing).

How do you get tested for MODY diabetes?
A blood sugar test is the first step toward diagnosing MODY. If your results indicate you have diabetes, your doctor may order additional tests to determine if you have MODY or another type of diabetes, such as type 1 or 2. Since MODY is caused by a genetic mutation, a genetic test can also help diagnose it.
When do you suspect MODY?
A clinical diagnosis of MODY can be suspected in individuals with: Early-onset diabetes in adolescence or young adulthood (typically age <35 years); Features atypical for type 1 diabetes mellitus including the following: Absence of pancreatic islet autoantibodies [McDonald et al 2011a]
How common is MODY?
Signs and symptoms MODY is the final diagnosis in 1%–2% of people initially diagnosed with diabetes. The prevalence is 70–110 per million people. 50% of first-degree relatives will inherit the same mutation, giving them a greater than 95% lifetime risk of developing MODY themselves.
How many types of MODY are there?
The different types of MODY are distinguished by their genetic causes. The most common types are HNF1A-MODY (also known as MODY3), accounting for 50 to 70 percent of cases, and GCK-MODY (MODY2), accounting for 30 to 50 percent of cases.
When should you suspect monogenic diabetes?
Doctors consider factors that may suggest monogenic diabetes: Being diagnosed in the first six months of life. Having other conditions caused by a specific gene mutation, such as cysts in the kidneys. Not being obese, or having diabetic family members who are normal weight.
When do you suspect MODY diabetes?
MODY can be suspected and recognized if a type 2 diabetes–like condition occurs in two to three or more generations and the pattern of inheritance is consistent with autosomal-dominant inheritance (6,7). The latter is the hallmark of MODY and distinguishes it from type 2 diabetes.
Which MODY is most common?
Is MODY a type 1 diabetic?
MODY is a rare form of diabetes which is different from both type 1 and type 2 diabetes, and runs strongly in families. MODY is caused by a mutation (or change) in a single gene. If a parent has this gene mutation, any child they have, has a 50% chance of inheriting it from them.
