Gene: [17q253/SGSH] N-sulfoglucosamine sulfohydrolase (sulfamidase); sulphamidase, heparan sulfate sulfatase; mucopolysaccharidosis type IIIA (heparan sulfate sulfatase deficiency); SanFilippo syndrome A (heparan sulfate sulfatase deficiency);

CAG

[1] Four enzymatically distinct forms of mucopolysaccharidosis type III (SanFilippo syndrome) are now recognized: A - due to heparan sulfate sulfatase deficiency (this locus), B - due to alpha-N-acetylglucosaminidase deficiency (GEM:17q21/NAGLU), C - due to alpha-glucosaminide N-acetyltransferase deficiency (GEM:00.0/AGNAT), D - due to N-acetylglucosamine-6-sulfatase deficiency (GEM:12q14/GNS).
[2] About mucopolysaccharidosis type I (due to alpha-L-iduronidase deficiency) see GEM:04p163/IDUA."
