What is the official name of the SGSH gene?
The official name of this gene is “N-sulfoglucosamine sulfohydrolase.”
SGSH is the gene's official symbol. The SGSH gene is also known by other names, listed below.

What is the normal function of the SGSH gene?
The SGSH gene provides instructions for producing an enzyme called sulfamidase. This enzyme is located in lysosomes, compartments within cells that digest and recycle different types of molecules. Sulfamidase is involved in the step-wise breakdown of large molecules called glycosaminoglycans (GAGs). GAGs are composed of sugar molecules that are linked together to form a long string. To break down these large molecules, individual sugars are removed one at a time from one end of the molecule. Sulfamidase removes a sulfate molecule from a sugar called glucosamine when it is at the end of the GAG chain.
