Mucopolysaccharidosis type VI (MPS VI) is an autosomal recessive disease caused by a deficiency of N-acetylgalactosamine 4-sulfatase (4S) leading to the lysosomal accumulation and urinary excretion of dermatan sulfate. MPS VI has also been described in the Siamese cat. As an initial step toward
BACKGROUND
Application of metabolic phenotyping could expand the pathophysiological knowledge of mucopolysaccharidoses (MPS) and may reveal the comprehensive metabolic impairments in MPS. However, few studies applied this approach to MPS.
METHODS
We applied targeted and untargeted metabolic
Mucopolysaccharidosis type VI (MPS VI; Maroteaux-Lamy disease) results from the deficient activity of the lysosomal enzyme, arylsulfatase B (ASB; N-acetylgalactosamine-4-sulfatase E.C.3.1.6.1). The enzymatic defect leads to the accumulation of the glycosaminoglycan, dermatan sulfate, primarily in
BACKGROUND
Metabolomics represent a valuable tool to recover biological information using body fluids and may help to characterize pathophysiological mechanisms of the studied disease. This approach has not been widely used to explore inherited metabolic diseases. This study investigates
Mucopolysaccharidosis type VI, or Maroteaux-Lamy syndrome, is a lysosomal storage disorder caused by a deficiency of the enzyme arylsulfatase B (ASB), also known as N-acetylgalactosamine-4-sulfatase. Multiple clinical phenotypes of this autosomal recessively inherited disease have been described.
Metabolic phenotyping is poised as a powerful and promising tool for biomarker discovery in inherited metabolic diseases. However, few studies applied this approach to mcopolysaccharidoses (MPS). Thus, this innovative functional approach may unveil comprehensive impairments in MPS biology. This
Mucopolysaccharidosis VI (MPS-VI) is an infrequent autosomal recessive disorder caused by mutations in ARSB gene and deficiency in lysosomal enzyyme ARSB activities subsequently. This enzyme is essential for the breaking of glycosaminoglycans (GAGs) such as dermatan sulfate and chondroitin sulfate.
To identify mutations of iduronate-2-sulfatase (IDS) gene in a patient with Hunter syndrome and to establish a basis for prenatal gene diagnosis of Hunter syndrome. Urine GAG assay was used for preliminary diagnosis of mucopolysaccharidosis. PCR from dried blood spots and DNA sequencing were applied
Mucopolysaccharidosis type I (MPS-I) is an autosomal recessive genetic disease caused by a deficiency of the glycosidase alpha-L-iduronidase which is required for the lysosomal degradation of the glycosaminoglycans heparan sulfate and dermatan sulfate. Patients with MPS-I store forms of these
BACKGROUND
Molecular investigations of iduronate-2-sulfatase (IDS) mutants for the X-linked lysosomal storage disease mucopolysaccharidosis type II (MPS II, Hunter disease), commonly depends on transient expression studies to verify a single nucleotide change to be pathogenic. In 2 severely affected
Mucopolysaccharydosis IIIB is the second most frequent form of Sanfilippo syndrome, a degenerative, pediatric lysosomal storage disease (LSD) characterized by severe neurological disorders and death. We have generated two iPSCs lines derived from dermal fibroblast from a MPSIIIB homozygous (P358L)
