Summaries for Mucopolysaccharidosis Type Iiic

About this section
NIH Rare Diseases:45 Mucopolysaccharidosis type iiic (mps iiic) 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 iiic results from the missing or altered enzyme acetyl-coalpha-glucosaminide acetyltransferase. this condition is inherited in an autosomal recessive manner. there is no specific treatment. most people with mps iiic live into their teenage years; some live longer. last updated: 4/14/2010

MalaCards based summary: Mucopolysaccharidosis Type Iiic, also known as mps iiic, is related to mucopolysaccharidosis and mucopolysaccharidosis iii, and has symptoms including hernia, cellular metachromasia and ovoid thoracolumbar vertebrae. An important gene associated with Mucopolysaccharidosis Type Iiic is HGSNAT (Heparan-Alpha-Glucosaminide N-Acetyltransferase). Affiliated tissues include skin, eye and bone.

UniProtKB/Swiss-Prot:67 Mucopolysaccharidosis 3C: 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.

OMIM:49 Sanfilippo syndrome comprises several forms of lysosomal storage diseases due to impaired degradation of heparan... (252930) more...
