What is the official name of the ADAMTSL2 gene?

The official name of this gene is “ADAMTS like 2.”

ADAMTSL2 is the gene's official symbol. The ADAMTSL2 gene is also known by other names, listed below.

What is the normal function of the ADAMTSL2 gene?

The ADAMTSL2 gene provides instructions for making a protein whose function is unknown. The ADAMTSL2 protein is active in many different tissues. It is found in the extracellular matrix, which is the intricate lattice of proteins and other molecules that forms in the spaces between cells.

Studies suggest that the ADAMTSL2 protein interacts with a protein called latent transforming growth factor beta binding protein 1 (LTBP1). The LTBP1 protein is involved in the storage of transforming growth factor beta (TGF-β), a critical growth factor that helps control the growth and division (proliferation) of cells, the process by which cells mature to carry out specific functions (differentiation), cell movement (motility), and the self-destruction of cells (apoptosis). Through its interaction with the LTBP1 protein, researchers suspect that the ADAMTSL2 protein may help regulate the availability of TGF-β.

The interaction between the ADAMTSL2 protein and the LTBP1 protein suggests that ADAMTSL2 may also play a role in the microfibrillar network. This organized clustering of thread-like filaments (called microfibrils) in the extracellular matrix provides strength and flexibility to tissues throughout the body.

How are changes in the ADAMTSL2 gene related to health conditions?

geleophysic dysplasia - caused by mutations in the ADAMTSL2 gene

At least five mutations in the ADAMTSL2 gene have been identified in people with geleophysic dysplasia. Most of these mutations change single protein building blocks (amino acids) in the ADAMTSL2 protein, which probably alters the protein's 3-dimensional shape.

Through a process that is poorly understood, ADAMTSL2 gene mutations alter the microfibrillar network in many different tissues. Impairment of this essential network disrupts the normal functions of cells, which likely contributes to the varied signs and symptoms of geleophysic dysplasia. Researchers are working to determine how mutations in the ADAMTSL2 gene lead to short stature, heart disease, and the other features of this condition.

Where is the ADAMTSL2 gene located?

Cytogenetic Location: 9q34.2

(Homo sapiens Annotation Release 107, GRCh38.p2) (NCBIThis link leads to a site outside Genetics Home Reference.)

The ADAMTSL2 gene is located on the long (q) arm of chromosome 9 at position 34.2.

The ADAMTSL2 gene is located on the long (q) arm of chromosome 9 at position 34.2.

More precisely, the ADAMTSL2 gene is located from base pair 133,532,164 to base pair 133,575,519 on chromosome 9.
