What is this test?

The ADAMTS2 gene targeted mutation analysis is a molecular genetics test that examines your DNA to find specific changes (mutations) in the ADAMTS2 gene. This gene provides instructions for making an enzyme called ADAMTS2 (A Disintegrin And Metalloproteinase with Thrombospondin motifs 2), which plays a crucial role in processing collagen molecules—the proteins that provide strength and flexibility to your body's connective tissues.

Why is this test performed?

This test is primarily used to confirm or rule out a diagnosis of dermatosparaxis Ehlers-Danlos syndrome (dEDS), a rare inherited connective tissue disorder. People with dEDS have mutations in both copies of their ADAMTS2 gene, leading to defective collagen processing. This results in extremely fragile skin, easy bruising, distinctive facial features, and other connective tissue-related symptoms.

How is the test done?

A healthcare professional will collect a blood sample from a vein in your arm, or in some cases, a tissue sample may be used. The sample is then sent to a specialized laboratory where molecular genetics techniques are used to analyze the ADAMTS2 gene for known disease-causing mutations. The test is specifically looking for targeted mutations rather than sequencing the entire gene.

What do the results mean?

If the test finds two pathogenic mutations (one from each parent), it confirms a diagnosis of dermatosparaxis EDS. Finding one mutation indicates carrier status. If no known mutations are found, it does not completely rule out the condition, as there may be unidentified mutations. A genetic counselor or geneticist should always interpret the results in the context of your personal and family medical history.
