Mucopolysaccharidosis type II
Other Names for this Disease
- Attenuated MPS (subtype; formerly known as mild MPS II)
- Hunter syndrome
- I2S deficiency
- Iduronate 2-sulfatase deficiency
- MPS 2
How is mucopolysaccharidosis II (MPS II) inherited?
Is carrier testing for mucopolysaccharidosis II (MPS II) available?
There are two types of MPS II, called the severe and attenuated types. While both types affect many different parts of the body, people with the severe type also experience a decline in intellectual function and a more rapid disease progression. The life expectancy for people with the severe type is 10 to 20 years. Individuals with the attenuated type typically live into adulthood and their intelligence is not affected. Heart disease and airway obstruction are major causes of death in people with both types of MPS II.
The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. Click here to link directly to a list of labs conducting carrier screening for MPS II. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.
