What is the official name of the ADAMTS13 gene?
The official name of this gene is “ADAM metallopeptidase with thrombospondin type 1 motif 13.”
ADAMTS13 is the gene's official symbol. The ADAMTS13 gene is also known by other names, listed below.

What is the normal function of the ADAMTS13 gene?
The ADAMTS13 gene provides instructions for making an enzyme that is involved in blood clotting. After an injury, clots normally protect the body by sealing off damaged blood vessels and preventing further blood loss.
The ADAMTS13 enzyme processes a large protein called von Willebrand factor, which also plays a role in clot formation. The unprocessed form of von Willebrand factor interacts easily with cell fragments called platelets, which circulate in the bloodstream and are essential for blood clotting. The factor helps platelets stick together and adhere to the walls of blood vessels, forming temporary clots. The ADAMTS13 enzyme cuts von Willebrand factor into smaller pieces. By processing von Willebrand factor in this way, the enzyme prevents it from triggering the formation of unnecessary blood clots.
Does the ADAMTS13 gene share characteristics with other genes?
The ADAMTS13 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.
