Summaries for Mucopolysaccharidosis, Type Iiib

NIH Rare Diseases : 53 Mucopolysaccharidosis type IIIB (MPS IIIB) is an genetic disorder that makes the body unable to break down large sugar molecules called glycosaminoglycans (GAGs, formerly called mucopolysaccharides). Specifically, people with this condition are unable to break down a GAG called heparan sulfate. Affected individuals can have severe neurological symptoms, including progressive dementia, aggressive behavior, hyperactivity, seizures, deafness, loss of vision, and an inability to sleep for more than a few hours at a time. MPS IIIB is caused by alterations (mutations) in the NAGLU gene. This gene provides the instructions for producing an enzyme called N-alpha-acetylglucosaminidase, which is needed to completely break down heparan sulfate. MPS IIIB is inherited in an autosomal recessive manner. There is no specific treatment for this condition. Most people with MPS IIIB live into their teenage years, and some live longer.

MalaCards based summary : Mucopolysaccharidosis, Type Iiib, also known as mucopolysaccharidosis type iiib, is related to mucopolysaccharidosis iii and mucopolysaccharidosis-plus syndrome, and has symptoms including seizures, joint stiffness and diarrhea. An important gene associated with Mucopolysaccharidosis, Type Iiib is NAGLU (N-Acetyl-Alpha-Glucosaminidase), and among its related pathways/superpathways is Lysosome. The drugs insulin and Insulin, Globin Zinc have been mentioned in the context of this disorder. Affiliated tissues include brain, spinal cord and bone, and related phenotypes are intellectual disability and seizures

OMIM : 57 Sanfilippo syndrome B is an autosomal recessive lysosomal storage disorder characterized by the accumulation of heparan sulfate. Clinically, patients have progressive neurodegeneration, behavioral problems, mild skeletal changes, and shortened life span. The clinical severity ranges from mild to severe (Chinen et al., 2005). For a phenotypic description and a discussion of genetic heterogeneity of Sanfilippo syndrome, or mucopolysaccharidosis III, see MPS IIIA (252900). (252920)

UniProtKB/Swiss-Prot : 74 Mucopolysaccharidosis 3B: A form of mucopolysaccharidosis type 3, an autosomal recessive lysosomal storage disease due to impaired degradation of heparan sulfate. MPS3 is characterized by severe central nervous system degeneration, but only mild somatic disease. Onset of clinical features usually occurs between 2 and 6 years; severe neurologic degeneration occurs in most patients between 6 and 10 years of age, and death occurs typically during the second or third decade of life.
