Summaries for Mucopolysaccharidosis-Plus Syndrome

NIH Rare Diseases : 53 Mucopolysaccharidosis refers to a group of inherited conditions in which the body is unable to properly breakdown mucopolysaccharides (long chains of sugar molecules that are found throughout the body). As a result, these sugars buildup in cells, blood and connective tissue which can lead to a variety of health problems. Seven distinct forms and numerous subtypes of mucopolysaccharidosis have been identified. Associated signs and symptoms and the severity of the condition vary significantly by form. In general, most affected people appear healthy at birth and experience a period of normal development, followed by a decline in physical and/or mental function. As the condition progresses, it may affect appearance; physical abilities; organ and system functioning; and, in most cases, cognitive development. The underlying genetic cause varies by form. Most cases are inherited in an autosomal dominant manner, although one specific form (Type II) follows an X-linked pattern of inheritance. Treatment is based on the signs and symptoms present in each person.

MalaCards based summary : Mucopolysaccharidosis-Plus Syndrome, also known as mucopolysaccharidosis, is related to mucopolysaccharidosis, type iva and mucopolysaccharidosis, type ii. An important gene associated with Mucopolysaccharidosis-Plus Syndrome is VPS33A (VPS33A, CORVET/HOPS Core Subunit), and among its related pathways/superpathways are Glycosaminoglycan degradation and Lysosome. Affiliated tissues include bone, skin and heart, and related phenotypes are tubular atrophy and proteinuria

OMIM : 57 MPSPS is an autosomal recessive inborn error of metabolism resulting in a multisystem disorder with features of the mucopolysaccharidosis lysosomal storage diseases (see, e.g., 607016). Patients present in infancy or early childhood with respiratory difficulties, cardiac problems, anemia, dysostosis multiplex, renal involvement, coarse facies, and delayed psychomotor development. Most patients die of cardiorespiratory failure in the first years of life (summary by Kondo et al., 2017). (617303)

UniProtKB/Swiss-Prot : 75 Mucopolysaccharidosis-plus syndrome: A form of mucopolysaccharidosis, a group of diseases characterized by excessive accumulation and secretion of oligomucopoloysaccharides. MPSPS is a multisystemic disorder characterized by coarse facial features, dysostosis multiplex, hepatosplenomegaly, respiratory difficulties, mental retardation, developmental delay, pyramidal signs, severe chronic anemia, renal involvement and cardiac defects. Laboratory analyses show proteinuria with glomerular foamy cells, excess secretion of urinary glycosaminoglycans, and extremely high levels of plasma heparan sulphate. Disease onset is in infancy. Most patients die in the first years of life due to cardiorespiratory failure. MPSPS inheritance is autosomal recessive.

Disease Ontology : 12 A lysosomal storage disease that involves the accumulation of glycosaminoglycans in the tissues and their excretion in the urine.
