We discovered a new spontaneous mutant allele of Npr2 named peewee (pwe) that exhibits severe disproportionate dwarfism and female infertility. The pwe phenotype is caused by a four base-pair deletion in exon 3 that generates a premature stop codon at codon 313 (L313X). The Npr2(pwe/pwe) mouse is a model for the human skeletal dysplasia acromesomelic dysplasia, Maroteaux type (AMDM). We conduct...
Maroteaux-Lamy syndrome, or mucopolysaccharidosis VI (MPS VI), is an autosomal recessive lysosomal storage disorder caused by a deficiency of N-acetylgalactosamine-4-sulfatase or arylsulfatase B (ARSB). We aimed to analyze the spectrum of mutations responsible for the disorder in Spanish and Argentinian patients, not previously studied. We identified all the ARSB mutant alleles, nine of them no...
involves the fibroblast growth-factor receptor 3 gene. Blood 10:4062, 1997 9. Tavormina PL, Shiang R, Thompson LM, Zhu YZ, Wilkin DJ, Lachman RS, Wilcox WR, Rimoin DL, Cohn DH, Wasmuth JJ: Thanatophoric dysplasia (types I and II) caused by distinct mutations in fibroblast growth factor receptor 3.

The syndrome of short stature inherited as an X-linked recessive trait was first reported by Jacobsen (1939) who described one family under the title 'hereditary osteochondrodystrophia deformans'. Three more pedigrees were studied by Maroteaux, Lamy, and Bernard (1957), who proposed the name dysplasia spondyloepiphysaire tardive, or spondyloepiphyseal dysplasia tarda (SDT). These authors also d...
The biosynthesis and maturation of N-acetylgalactosamine-4-sulphatase (4-sulphatase) was studied in normal fibroblasts and in fibroblasts from patients with either mucopolysaccharidosis type VI (MPS VI; Maroteaux-Lamy syndrome) or multiple sulphatase deficiency (MSD). Fibroblasts were incubated in culture medium containing [3H]leucine or [35S]methionine, and radiolabelled 4-sulphatase was isola...
Mucopolysaccharidosis VI (MPS VI, Maroteaux-Lamy syndrome) is caused by deficient activity of the enzyme, N-acetylgalactosamine-4-sulfatase, resulting in impaired degradation of the glycosaminoglycan dermatan sulfate. Patients experience a range of manifestations including joint contractures, short stature, dysostosis multiplex, coarse facial features, decreased pulmonary function, cardiac abno...
Asphyxiating thoracic dystrophy of the newborn is a rare skeletal abnormality. Though the disease is generalized in distribution, the cartilaginous thoracic cage bears the brunt, with the results that the chest is narrow and immobile. The outcome is usually fatal early in the neonatal period. Less frequently the patients survive with severely impaired respiratory function only to succumb to rep...

INTRODUCTION Mucopolysaccharidosis type VI (MPS VI, Maroteaux-Lamy syndrome) is an autosomal recessive lysosomal storage disorder, characterized primarily by skeletal dysplasia and joint contracture. It is caused by a deficiency of N-acetylgalactosamine-4-sulfatase (arylsulfatase B), for which a recombinant formulation (galsulfase) is available as replacement therapy. OBJECTIVE To evaluate th...
Staining with Alcian blue in various concentrations of magnesium chloride (alcianophilia) has been found to be a useful supplement to metachromatic staining to detect increased cellular concentrations of glycosaminoglycans (mucopolysaccharides). In many instances alcianophilia at 0.3 M MgCl(2) is more specific than metachromasia and does not give "false positives" sometimes found in normal indi...
