Summary: The product of this gene is a lysosomal enzyme found in all cells. It is involved in the catabolism of heparin, heparan sulphate, and keratan sulphate. Deficiency of this enzyme results in the accumulation of undegraded substrate and the lysosomal storage disorder mucopolysaccharidosis type IIID (Sanfilippo D syndrome). Mucopolysaccharidosis type IIID is the least common of the four subtypes of Sanfilippo syndrome. [provided by RefSeq, Jul 2008]
Expression: Ubiquitous expression in adrenal (RPKM 76.5), kidney (RPKM 63.0) and 24 other tissues See more

What's a GeneRIF?

Mice deficient in GNS showed lysosomal storage pathology and a phenotype that closely resembled human MPSIIID. Moreover, treatment of the GNS-deficient animals with GNS-encoding adeno-associated viral (AAV) vectors of serotype 9 delivered to the cerebrospinal fluid completely corrected pathological storage, improved lysosomal functionality in the CNS and somatic tissues, resolved neuroinflammation

12 new patients and 15 novel mutations were identified in Mucopolysaccharidosis type IIID.
Title: Mucopolysaccharidosis type IIID: 12 new patients and 15 novel mutations.
We identified the novel homozygous single base pair insertion, c.1226GinsG, which leads to a frame-shift and a premature truncation of the GNS protein (p.R409Rfs21X).
Title: A novel loss-of-function mutation in the GNS gene causes Sanfilippo syndrome type D.
Sanfilippo syndrome type D has 3 novel mutations in the GNS Gene.
Title: Sanfilippo syndrome type D: natural history and identification of 3 novel mutations in the GNS Gene.
A large intragenic deletion of 8723 bp encompassing exons 2 and 3 has been identified, the first large intragenic deletion to be reported in any of the four Sanfilippo subtypes. Q272X has also been found.
Title: Identification and characterisation of an 8.7 kb deletion and a novel nonsense mutation in two Italian families with Sanfilippo syndrome type D (mucopolysaccharidosis IIID).
The Sanfilippo syndrome type D patient was found to be homozygous for a single base pair deletion (c1169delA), which will cause a frameshift and premature termination of N-acetylglucosamine-6-sulphatase.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
