What is abnormal MPS?

Mucopolysaccharidosis type I (MPS I) is a rare disease in which the body is missing or does not have enough of an enzyme needed to break down long chains of sugar molecules. These chains of molecules are called glycosaminoglycans (formerly called mucopolysaccharides).

What disease is MPS?

The mucopolysaccharidoses (MPS) are a group of inherited lysosomal storage disorders. Lysosomes function as the primary digestive units within cells. Enzymes within lysosomes break down or digest particular nutrients, such as certain carbohydrates and fats.

What are the symptoms of mucopolysaccharidosis?


  • Enlarged head, lips, cheeks, tongue, and nose.
  • Enlarged vocal cords, resulting in a deep voice.
  • Frequent upper respiratory infections.
  • Sleep apnea.
  • Hydrocephalus.
  • Hepatosplenomegaly (enlarged liver and spleen)
  • Umbilical hernia.
  • Inguinal hernia.

What is the life expectancy of someone with Hunter syndrome?

No cure is available for Hunter syndrome. The most severe cases can be life-threatening, with life expectancy typically between 10 and 20 years. People with mild cases of the disease typically live longer into adulthood.

What are mucopolysaccharides examples?

Chondroitin sulphate and heparin are examples for mucopolysaccharides from animal sources used for inner and outer medical applications. The chemical composition of these polymers depends strongly on the derived source (animal or plant species).

Is mucopolysaccharidosis a genetic disorder?

Mucopolysaccharidosis type I (MPS I) is a rare genetic disorder that affects many parts of the body (multisystem).

What type of doctor treats Hunter syndrome?

Research is under way to find effective treatments for boys with severe Hunter syndrome. Treating the symptoms. Because so many different parts of your child’s body can be affected, you’ll probably need to see several doctors to help you manage the condition, including: Cardiologist: a heart specialist.

What are the types of mucopolysaccharidosis?


  • Mucopolysaccharidosis type I (Hurler syndrome)
  • Mucopolysaccharidosis type II (Hunter syndrome)
  • Mucopolysaccharidosis type III (Sanfilippo syndrome)
  • Mucopolysaccharidosis type IV (Morquio syndrome)
  • Mucopolysaccharidosis type VI (Maroteaux-Lamy syndrome)
  • Mucopolysaccharidosis type VII (Sly syndrome)

What causes Mucopolysaccharidosis Type IX ( MPS IX )?

Mucopolysaccharidosis Type IX is an extremely rare disorder that may be caused by inheriting faulty genes that prevents the body from producing a certain enzyme, known as the hyaluronidase enzyme. The gene responsible for MPS IX is the HYAL1 gene. The condition is believed to be inherited in an autosomal recessive manner

What are the symptoms of mucopolysaccharidosis type VII?

Sly syndrome (mucopolysaccharidosis type VII; MPS VII) is characterized by a deficiency of the enzyme beta-glucuronidase, resulting in the accumulation of three glycosaminoglycans: dermatan sulfate, heparan sulfate and chondroitin sulfate. The symptoms may vary greatly from person to person.

Can a child with mucopolysaccharidoses pass on the disorder?

The parents and siblings of an affected child may have no sign of the disorder. Unaffected siblings and select relatives of a child with one of the mucopolysaccharidoses may carry one copy of the defective gene and could pass it on to their own children. (The one exception is MPS II, or Hunter syndrome, which is an X-linked recessive disorder.

How many types of mucopolysaccharidoses are there in the world?

Seven distinct clinical types and numerous subtypes of the mucopolysaccharidoses have been identified. Although each mucopolysaccharidosis (MPS) differs clinically, most individuals experience a period of normal development followed by a decline in physical and/or mental function.
