Hunter syndrome
Alternate Names : Mucopolysaccharidosis type II, Iduronate sulfatase deficiency
Definition
Hunter syndrome is an inherited disease in which long chains of sugar molecules (mucopolysaccharides) are not broken down correctly and build up in the body.
Overview, Causes, & Risk Factors
Hunter syndrome is an inherited condition. Boys are most often affected. The condition is caused by a lack of the enzyme iduronate sulfatase. Without this enzyme, mucopolysaccharides build up in various body tissues, causing damage. The early-onset, severe form of the disease begins shortly after age 2. A late-onset, mild form causes less severe symptoms to appear later in life.
