IDUA
Involvement in disease
Mucopolysaccharidosis 1H
MPS1H
A severe form of mucopolysaccharidosis type 1, a rare lysosomal storage disease characterized by progressive physical deterioration with urinary excretion of dermatan sulfate and heparan sulfate. Patients with MPS1H usually present, within the first year of life, a combination of hepatosplenomegaly, skeletal deformities, corneal clouding and severe intellectual disability. Obstructive airways disease, respiratory infection and cardiac complications usually result in death before 10 years of age.
None
The disease is caused by variants affecting the gene represented in this entry.
Mucopolysaccharidosis 1H/S
MPS1H/S
A form of mucopolysaccharidosis type 1, a rare lysosomal storage disease characterized by progressive physical deterioration with urinary excretion of dermatan sulfate and heparan sulfate. MPS1H/S represents an intermediate phenotype of the MPS1 clinical spectrum. It is characterized by relatively little neurological involvement, but most of the somatic symptoms described for severe MPS1 develop in the early to mid-teens, causing considerable loss of mobility.
None
The disease is caused by variants affecting the gene represented in this entry.
Mucopolysaccharidosis 1S
MPS1S
A mild form of mucopolysaccharidosis type 1, a rare lysosomal storage disease characterized by progressive physical deterioration with urinary excretion of dermatan sulfate and heparan sulfate. Patients with MPS1S may have little or no neurological involvement, normal stature and life span, but present development of joints stiffness, mild hepatosplenomegaly, aortic valve disease and corneal clouding.
None
The disease is caused by variants affecting the gene represented in this entry.
Post-translational modifications
N-glycosylation at Asn-372 contributes to substrate binding and is required for full enzymatic activity.
Sequence Similarities
Belongs to the glycosyl hydrolase 39 family.
Tissue Specificity
Ubiquitous.
Cellular localization
- Lysosome
Alternative names
Alpha-L-iduronidase, IDUA
