Definition

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.
