  Purpose

Approximately 85% of individuals with Mucopolysaccharidosis (MPS) type I, II, or VI report weekly pain and 50-60% have significant limitations in their activities of daily living due to MPS related musculoskeletal disease despite treatment with enzyme replacement therapy (ERT). Thus there is a critical need to identify additional therapies to alleviate the burden of musculoskeletal disease in order to improve the health and quality of life of individuals with MPS. However, disease progression needs to be quantified to be able to determine efficacy of new therapies. This study is a multi-institutional, 5-year, longitudinal study of musculoskeletal disease in MPS. The objective is to quantitatively describe the progression of skeletal disease and identify biomarkers that either predict disease severity or could be used as therapeutic targets in individuals with MPS I, II, and VI. A database of standardized measurements of musculoskeletal disease in MPS will allow the field to efficiently move forward with therapeutic clinical trials in patients with MPS.

Criteria

Inclusion Criteria:

  • Diagnosis of MPS I, II, or VI
  • Ability to travel to study center for evaluations.
  • Age ≥ 5 years and < 35 years: age at entry into study must be ≥5 years and ≤33 years to ensure a minimum of 2 study visits.

Exclusion Criteria:

  • Pregnancy (will be determined at each study visit)
  • Participation in any other study within the past 12 months which would result in increasing the child's radiation exposure above 500 mrem for the calendar year.
  • Participants who cannot comply with study procedures or have other factors that would inhibit their participation as determined by the PI's discretion.
