Mucopolysaccharidoses (MPS) comprise a group of lysosomal disorders that are characterized by progressive, systemic clinical manifestations and a coarse phenotype. The different types, having clinical, biochemical, and genetic heterogeneity, share key clinical features in varying combinations, including joint and skeletal dysplasia, coarse facial features, corneal clouding, inguinal or. Mucopolysaccharidoses (MPSs) are a group of uncommon genetic diseases of connective tissue metabolism. It is well established that the elective treatment of subjects affected by MPS is multidisciplinary and must be carried out by experienced personnel in highly specialist centers. However, there is the possibility to perform an anesthesia in a peripheral center, where anesthesiologists might. The study tests for 4 of the types of MPS: I, II, IVA, and VI. This can help researchers decide whether to create a screening program for MPS at pediatric rheumatology clinics. This study is being done in rheumatology clinics because the first symptoms of MPS are often joint problems such as stiff joints, and rheumatologists may be the first. Mucopolysaccharidoses is a family of metabolic disorders caused by the absence or irregular functioning of lysosomal enzymes required to degrade glycosaminoglycans. Mucopolysaccharidosis IVA (MPS IVA or Morquio A syndrome) is characterized by the functional loss of the enzyme N-­‐acetylgalactosamine-­‐6-­‐ sulfatase (GALNS). The absence of GALNS leads to the chronic accumulation of.

Morquio B disease (MBD) is an autosomal recessive GLB1-gene-related lysosomal storage disease, presenting with a peculiar type of dysostosis multiplex which is also observed in GALNS-related Morquio A disease. MBD may present as pure skeletal phenotype (pure MBD) or in combination with the neuronopathic manifestations seen in type 2 (juvenile) or type 3 (late onset) GM1 gangliosidosis (MBD. Patients with MPS IVA have an absence or marked reduction of GALNS activity, which leads to the accumulation of the glycosaminoglycan (GAG) substrates keratan sulfate (KS) and chondroitin-6-sulfate (C6S). Patients experience widespread tissue and organ damage, but the course of progression and severity is variable Morquio A syndrome, or mucopolysaccharidosis IVA (MPS IVA) is a disease in which people are missing an enzyme that is essential in the breakdown and removal of the glycosaminoglycans (GAGs) called keratan sulfate (KS) and chondroitin-6-sulfate (C6S). The incompletely broken down GAGs remain stored in cells in the body causing progressive damage MPS VI and VII ( 253220) were more rare and accounted for 1.7% and 1.3%, respectively. A retrospective epidemiologic data collection was performed in Switzerland between 1975 and 2008 (34 years), and 41 living MPS patients were identified.
