Gene: SGSH

Alternate names for this Gene: HSS|MPS3A|SFMD

Gene Summary: This gene encodes the enzyme sulfamidase; one of several enzymes involved in the lysosomal degradation of heparan sulfate. Mutations in this gene are associated with the lysosomal storage disease mucopolysaccaridosis IIIA, also known as Sanfilippo syndrome A, which results from impaired degradation of heparan sulfate. Transcripts of varying sizes have been reported but their biological validity has not been determined.

Gene is located in Chromosome: 17

Location in Chromosome : 17q25.3

Description of this Gene: N-sulfoglucosamine sulfohydrolase

Type of Gene: protein-coding
