Summary
Brief summary
The purpose of the study is to prospectively assess longitudinal changes in proteolipid
protein 1 (PLP1) protein, disease-related biomarkers in cerebral spinal fluid (CSF) and
blood, neuroimaging parameters relevant to Pelizaeus-Merzbacher disease (PMD) and
longitudinal changes in performance on clinical, participant, and caregiver-reported outcome
assessments to inform the development of therapies for PMD.
