What is the official name of the ARSB gene?
The official name of this gene is “arylsulfatase B.”
ARSB is the gene's official symbol. The ARSB gene is also known by other names, listed below.
Read more about gene names and symbols on the About page.
What is the normal function of the ARSB gene?
The ARSB gene provides instructions for producing an enzyme called arylsulfatase B, which is involved in the breakdown of large sugar molecules called glycosaminoglycans (GAGs). Specifically, arylsulfatase B removes the sulfate molecule from two GAGs called dermatan sulfate and chondroitin sulfate. Arylsulfatase B is located in lysosomes, compartments within cells that digest and recycle different types of molecules.
How are changes in the ARSB gene related to health conditions?
Where is the ARSB gene located?
