What is the official name of the ADAMTS2 gene?

The official name of this gene is “ADAM metallopeptidase with thrombospondin type 1 motif, 2.”

ADAMTS2 is the gene's official symbol. The ADAMTS2 gene is also known by other names, listed below.

What is the normal function of the ADAMTS2 gene?

The ADAMTS2 gene provides instructions for making an enzyme that processes several types of procollagen molecules. Procollagens are the precursors of collagens, which are complex molecules that add strength, support, and elasticity (the ability to stretch) to many body tissues. Specifically, the ADAMTS2 enzyme clips a short chain of protein building blocks (amino acids) off one end of procollagens. This clipping step is necessary for the resulting collagen molecules to assemble into strong, slender fibrils outside cells.

Does the ADAMTS2 gene share characteristics with other genes?

The ADAMTS2 gene belongs to a family of genes called ADAMTS (ADAMTS metallopeptidase with thrombospondin type 1 motif).

A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? ( in the Handbook.

How are changes in the ADAMTS2 gene related to health conditions?

Ehlers-Danlos syndrome - caused by mutations in the ADAMTS2 gene

Several mutations in the ADAMTS2 gene have been identified in people with a form of Ehlers-Danlos syndrome called the dermatosparaxis type. These mutations greatly reduce the production or activity of the enzyme made by the ADAMTS2 gene. Procollagens cannot be processed correctly without this enzyme. As a result, collagen fibrils are not assembled properly; they appear ribbon-like and disorganized under the microscope. Cross-links, or chemical interactions, between collagen fibrils are also disrupted. These defects weaken connective tissue (the tissue that binds and supports the body's muscles, ligaments, organs, and skin), which causes the signs and symptoms of the disorder.

Where is the ADAMTS2 gene located?

Cytogenetic Location: 5qter

Molecular Location on chromosome 5: base pairs 179,110,850 to 179,345,429

The ADAMTS2 gene is located on the long (q) arm of chromosome 5 at the end (terminus) of the arm.

The ADAMTS2 gene is located on the long (q) arm of chromosome 5 at the end (terminus) of the arm.

More precisely, the ADAMTS2 gene is located from base pair 179,110,850 to base pair 179,345,429 on chromosome 5.
