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
Gene: TRAPPC2L
Alternate names for this Gene: HSPC176|PERRB
Gene Summary: This gene encodes a protein that interacts with the tethering factor trafficking protein particle (TRAPP complex). TRAPP complexes mediate the contact between vescicles and target membranes, and thus, are involved in vescicle-mediated transport of proteins and lipids. The encoded protein is related to the X-linked trafficking protein particle complex 2. A related pseudogene is located on the X chromosome. Alternative splicing results in multiple transcript variants encoding different isoforms.
