Sanfilippo B syndrome (MPS III B): mild and severe forms within the same sibship. 1979

G Andria, and P Di Natale, and E Del Giudice, and P Strisciuglio, and P Murino

Clinical heterogeneity for Sanfilippo B syndrome (MPS III B) in the same family has never been reported previously. We describe two clinically severe cases and one clinically mild case of MPS III B in a Neapolitan sibship. We could not detect N-acetyl-alpha-D-glucosaminidase activity in the sera of either the severe or mild cases. Mucopolysacchariduria mainly due to heparan sulfate excretion was consistently high in the severely affected patients and extremely variable in the mildly affected one.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008607	Intellectual Disability	Subnormal intellectual functioning which originates during the developmental period. This has multiple potential etiologies, including genetic defects and perinatal insults. Intelligence quotient (IQ) scores are commonly used to determine whether an individual has an intellectual disability. IQ scores between 70 and 79 are in the borderline range. Scores below 67 are in the disabled range.

D009083	Mucopolysaccharidoses	Group of lysosomal storage diseases each caused by an inherited deficiency of an enzyme involved in the degradation of glycosaminoglycans (mucopolysaccharides). The diseases are progressive and often display a wide spectrum of clinical severity within one enzyme deficiency.	Mucopolysaccharidosis
D009084	Mucopolysaccharidosis III	Mucopolysaccharidosis characterized by heparitin sulfate in the urine, progressive mental retardation, mild dwarfism, and other skeletal disorders. There are four clinically indistinguishable but biochemically distinct forms, each due to a deficiency of a different enzyme.

D006025	Glycosaminoglycans	Heteropolysaccharides which contain an N-acetylated hexosamine in a characteristic repeating disaccharide unit. The repeating structure of each disaccharide involves alternate 1,4- and 1,3-linkages consisting of either N-acetylglucosamine (see ACETYLGLUCOSAMINE) or N-acetylgalactosamine (see ACETYLGALACTOSAMINE).
