" /> Mucopolysaccharidosis, type iiid - CISMeF





Preferred Label : Mucopolysaccharidosis, type iiid;

Symbol : MPS3D;

CISMeF acronym : MPS3D;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : N-acetylglucosamine-6-sulfatase deficiency; Mps iiid; Sanfilippo syndrome D;

Description : The mucopolysaccharidoses are a family of lysosomal storage diseases caused by deficiencies of enzymes required for the catabolism of glycosaminoglycans. The defects result in accumulation of excessive intralysosomal glycosoaminoglycans (mucopolysaccharides) in various tissues, causing distended lysosomes to accumulate in the cell and interfere with cell function. Multiple types have been described (Mok et al., 2003).;

Inheritance : Autosomal recessive;

Molecular basis : Caused by mutation in the N-acetylglucosamine-6-sulfatase gene (GNS, 607664.0001);

Laboratory abnormalities : N-acetylglucosamine-6-sulfate sulfatase deficiency; Heparan sulfate excretion in urine; Metachromasia of white blood cells and fibroblasts;

Prefixed ID : #252940;
