CME: Treatment strategies in Hunter Syndrome


Activity Description / Statement of Need:

In this online CME self-learning program:

Mucopolysaccaridoses (MPS) are group of genetic disease characterized by a deficiency of lysosomal enzymes responsible for the hydrolysis of glycosaminoglycans (GAGs), whose manifold biological roles resulting in a variety of clinical manifestations in patients presenting with MPS. MPS has seven different subcategories, of which Hunter syndrome is MPS II. A deficiency in iduronate 2-sulfatase results in relatively high levels of the GAGs heparan and dermatan sulfate, resulting in physical signs similar to MPS I with the addition of aggressive behavior and developmental delay. Hunter syndrome is an X-linked recessive genetic disease, with males more likely to develop disease and females more likely to be carriers.

Target Audience:

The following healthcare professionals: Pediatricians, neurologists, endocrinologists and primary care physicians; physician assistants, nurse practitioners, nurses, and pharmacists; and any other healthcare professionals with an interest in or who may clinically encounter patients with Hunter syndrome.

This program is supported by an educational grant from Takeda/Shire.

Learners may participate in this activity free of charge.

Release Date: October 02, 2020 -- Expiration Date: October 02, 2022

Faculty: Natalia Gomez-Ospina, MD, PhD
