Resumen

Hunter syndrome (Mucopolysaccharidosis II, \[MPS II\]) is a rare, genetically linked lysosomal storage disease (LSD) caused by deficiency of the enzyme, iduronate-2-sulfatase (I2S). Most MPS II patients will present with some degree of neurodevelopmental involvement, ranging from severe cognitive impairment and behavioral problems to mildly impaired cognition. This is an observational study; no investigational treatment will be administered. The primary objective of this study is to evaluate the neurodevelopmental status of pediatric patients with MPS II over time and to gain information to guide future treatment studies in this patient population.

The patient is male, and is at least 2 years of age and less than 18 years of age at the time of informed consent.
The patient must have sufficient auditory capacity at enrollment, with or without hearing aids, in the Investigator's judgment to complete the required protocol testing, and be compliant with wearing the aids on scheduled study visits.

The patient has a general conceptual ability score (GCA) or a developmental quotient on the cognitive scale below 55 at Screening.
The patient is participating in an interventional clinical trial or has participated in an interventional clinical trial within 30 days prior to enrollment; participation in non interventional observational studies is permitted.
