Summaries for SGSH Gene

Entrez Gene Summary for SGSH Gene

  • This gene encodes one of several enzymes involved in the lysosomal degradation of heparan sulfate. Mutations in this gene are associated with Sanfilippo syndrome A, one type of the lysosomal storage disease mucopolysaccaridosis III, which results from impaired degradation of heparan sulfate. Transcripts of varying sizes have been reported but their biological validity has not been determined. [provided by RefSeq, Jul 2008]

Disorders for SGSH Gene

  • Mucopolysaccharidosis 3A (MPS3A) [MIM:252900]: A severe 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. MPS3A is characterized by earlier onset, rapid progression of symptoms and shorter survival. {ECO:0000269 PubMed:11182930, ECO:0000269 PubMed:11793481, ECO:0000269 PubMed:12000360, ECO:0000269 PubMed:12702166, ECO:0000269 PubMed:15146460, ECO:0000269 PubMed:15637719, ECO:0000269 PubMed:15902564, ECO:0000269 PubMed:16311287, ECO:0000269 PubMed:17128482, ECO:0000269 PubMed:18407553, ECO:0000269 PubMed:21671382, ECO:0000269 PubMed:9158154, ECO:0000269 PubMed:9285796, ECO:0000269 PubMed:9401012, ECO:0000269 PubMed:9554748, ECO:0000269 PubMed:9744479}.
