Gene: IDUA
Alternate names for this Gene: IDA|MPS1|MPSI
Gene Summary: This gene encodes an enzyme that hydrolyzes the terminal alpha-L-iduronic acid residues of two glycosaminoglycans, dermatan sulfate and heparan sulfate. This hydrolysis is required for the lysosomal degradation of these glycosaminoglycans. Mutations in this gene that result in enzymatic deficiency lead to the autosomal recessive disease mucopolysaccharidosis type I (MPS I).
Gene is located in Chromosome: 4
Location in Chromosome : 4p16.3
Description of this Gene: alpha-L-iduronidase
Type of Gene: protein-coding
