Gene: GALNS

Alternate names for this Gene: GALNAC6S|GAS|GalN6S|MPS4A

Gene Summary: This gene encodes N-acetylgalactosamine-6-sulfatase which is a lysosomal exohydrolase required for the degradation of the glycosaminoglycans, keratan sulfate, and chondroitin 6-sulfate. Sequence alterations including point, missense and nonsense mutations, as well as those that affect splicing, result in a deficiency of this enzyme. Deficiencies of this enzyme lead to Morquio A syndrome, a lysosomal storage disorder.

Gene is located in Chromosome: 16

Location in Chromosome : 16q24.3

Description of this Gene: galactosamine (N-acetyl)-6-sulfatase

Type of Gene: protein-coding
