(Glycoprotein Storage Diseases; Mucopolysaccharidoses; MPS)



Treatment is focused on managing the symptoms caused by the missing enzymes. Specific treatment depends on the enzyme defect that your child has but options may include:
  • Dialysis—to remove substances from the blood
  • Physical therapy
  • Surgery
  • Medication
Other treatments may include:
  • Substrate synthesis inhibition therapy (SSI)—Medication that decreases the item that build up in the cells due to missing enzymes.
  • Enzyme replacement therapy (ERT)—Working enzymes are delivered through an IV to do the job of the defective enzymes.
  • Stem cell transplant—Stem cells are transplanted through IV to encourage the body to make the missing enzyme.
