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).
