Video Summary
Mucopolysaccharide storage disease type 2, also known as Hunter syndrome, is an inherited disorder caused by a deficiency in the iduronate sulfatase enzyme. This enzyme is responsible for breaking down glycosaminoglycans (GAGs) which are large molecules that include heparan sulfate and dermatan sulfate.
Deficiency in iduronate sulfatase results in GAGs accumulating in organs and tissues throughout the body, leading to a wide range of symptoms, such as developmental delay, hearing loss, respiratory difficulties, enlarged organs, and skin abnormalities. Treatment focuses on managing symptoms, and may include physical, occupational, and speech therapies, enzyme replacement therapy, and bone marrow transplantation.
