Patient Preparing : No special preparation is needed for this test.
Mucopolysaccharidosis VI, also known as Maroteaux-Lamy Syndrome, is a rare genetic disorder characterized by the deficiency of a specific enzyme called Aryl Sulfatase B. This enzyme is vital for breaking down large sugar molecules called glycosaminoglycans (GAGs). When Aryl Sulfatase B is deficient, GAGs accumulate in various tissues and organs in the body, leading to a range of symptoms and complications. The Aryl Sulfatase B test is a quantitative blood test that measures the levels of the Aryl Sulfatase B enzyme and plays a critical role in diagnosing Maroteaux-Lamy Syndrome.

What is Mucopolysaccharidosis VI (Maroteaux-Lamy Syndrome)?
Mucopolysaccharidosis VI (MPS VI) is one of a group of inherited metabolic disorders where there is an absence or malfunctioning of specific enzymes needed to break down molecules called glycosaminoglycans. In MPS VI, there is a deficiency of the enzyme Aryl Sulfatase B, which leads to the accumulation of dermatan sulfate, a type of GAG, in various tissues and organs. The accumulation of these molecules causes progressive damage and affects appearance, physical abilities, organ function, and, in severe cases, lifespan.
What are the Symptoms of MPS VI?
The symptoms of MPS VI can range from mild to severe and may include:
- Short stature
- Enlarged liver and spleen
- Heart valve abnormalities
- Joint stiffness and pain
- Skeletal abnormalities
- Vision and hearing problems
- Respiratory issues
- Reduced endurance

Why is the Aryl Sulfatase B Test Important?
Diagnosing MPS VI early is crucial for managing the condition effectively. The Aryl Sulfatase B test measures the activity of the Aryl Sulfatase B enzyme in the blood. Low levels of this enzyme suggest a diagnosis of MPS VI.
Who Should Get Tested?
Individuals with symptoms suggestive of MPS VI or with a family history of the condition should consider getting tested. Additionally, the test may be conducted for newborn screening in some cases.
Can MPS VI be Cured?
Currently, there is no cure for MPS VI. However, treatment options such as enzyme replacement therapy (ERT) can help manage the symptoms and improve the quality of life for individuals with MPS VI.
What are the Treatment Options for MPS VI?
Enzyme replacement therapy (ERT) is the primary treatment for MPS VI. It involves replacing the deficient enzyme with a synthetic version. Other treatments include physical therapy, surgical interventions for skeletal and joint problems, and supportive care for respiratory issues.
How is MPS VI Inherited?
MPS VI is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell must have mutations for a person to be affected. Typically, the parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.
Is Prenatal Testing Available for MPS VI?
Yes, prenatal testing is available for couples at increased risk of having a child with MPS VI. This includes procedures like chorionic villus sampling (CVS) or amniocentesis.
Which Doctor Should I Consult if I Suspect MPS VI or if the Aryl Sulfatase B Levels are Abnormal?
If you or a family member exhibit symptoms of MPS VI or have abnormal Aryl Sulfatase B levels, it is recommended to consult a geneticist or a specialist in metabolic disorders for further evaluation and management.
Are There Any Lifestyle Modifications that Can Help in Managing MPS VI?
While there are no specific lifestyle modifications that can cure MPS VI, physical therapy, and ensuring good nutrition can help in managing the symptoms and improving the quality of life for those affected.
What Support is Available for Families Affected by MPS VI?
Families affected by MPS VI can benefit from joining support groups and connecting with organizations that focus on metabolic disorders. This provides an opportunity to share experiences and access resources for managing the condition.
What Research is Being Done on MPS VI?
Research is ongoing into more effective treatments for MPS VI. Gene therapy and improvements in enzyme replacement therapy are areas of active research.
The Aryl Sulfatase B test is an essential diagnostic tool for Mucopolysaccharidosis VI or Maroteaux-Lamy Syndrome. This test measures the levels of the Aryl Sulfatase B enzyme in the blood, helping in the diagnosis of MPS VI. Early diagnosis is crucial for the management of this condition, and while there is currently no cure for MPS VI, treatment options such as enzyme replacement therapy can help manage the symptoms. Consulting a doctor for proper advice and management is essential for those affected by this disorder.
