What is this test?

The ACE gene mutation test is a genetic test that looks for specific changes (polymorphisms) in the ACE (Angiotensin-Converting Enzyme) gene. The ACE gene contains instructions for making an enzyme that plays a key role in regulating blood pressure and fluid balance in the body by converting angiotensin I to angiotensin II, a potent vasoconstrictor.

Why might I need this test?

Your healthcare provider may recommend this test if you have a family history of heart disease, high blood pressure, or other cardiovascular conditions. It may also be useful in understanding certain kidney conditions or in research settings for conditions like sarcoidosis. The test helps identify genetic variations that could influence your risk for certain diseases or how you might respond to certain medications.

How is the test performed?

A healthcare professional will collect a small sample of your blood, typically from a vein in your arm. The sample is then sent to a laboratory where molecular genetics methods are used to analyze your DNA and identify specific mutations in the ACE gene. The most commonly tested polymorphism is the insertion/deletion (I/D) variant, where a specific segment of DNA is either present (insertion) or absent (deletion).

What do the results mean?

The results will show which variant(s) of the ACE gene you have inherited. Common results include: DD (deletion/deletion), II (insertion/insertion), or ID (insertion/deletion). These variants can affect the levels of ACE enzyme in your blood. However, it's important to understand that having a particular variant does not mean you will definitely develop a disease. Your healthcare provider will interpret these results in the context of your overall health, family history, and other test results.
