Comment:
Mucopolysaccharidosis type I (MPS I) is a panethnic, chronic and progressive, autosomal recessive lysosomal storage disease in which degradation of the glycoaminoglycans (GAGs) dermatan and heparan sulphate is deficient. Currently three clinical syndromes are often referred to which, from severe through intermediate to mild phenotypes, are termed Hurler, Hurler-Scheie and Scheie. It is clear however that this is an oversimplification and that the full phenotypic spectrum of disease forms a continuum (PMID:18796143). |

Description: (OMIM) |
The mucopolysaccharidoses are a group of inherited disorders caused by a lack of specific lysosomal enzymes involved in the degradation of glycosaminoglycans (GAGs), or mucopolysaccharides. The accumulation of partially degraded GAGs causes interference with cell, tissue, and organ ... |
Clinical Description OMIM |
The clinical features of Hurler-Scheie syndrome include short stature, corneal clouding, joint stiffening, umbilical hernia, dysostosis multiplex, hepatosplenomegaly, and little to no intellectual dysfunction. Onset of symptoms occurs between ages 3 and 8 years. Survival to adulthood is ... |
Molecular genetics OMIM |
Bunge et al. (1995) identified 13 novel and 7 previously reported mutations of the IDUA gene, covering 88% of mutant alleles and 86% of genotypes, in a total of 29 patients with MPS I of differing clinical severity. ... |
