Summary

The goal of this observational study is to develop and validate tools to measure disease course in patients with primary mitochondrial myopathy (PMM). The main aims of this study are: * Development, validation, and optimization of objective outcome measures for mitochondrial myopathy * Defining the natural history of mitochondrial myopathy Researchers will compare data from patients with primary mitochondrial myopathy to healthy controls. Data from healthy controls will also help define normative data for future studies. Participants will perform clinical exams of muscle strength and endurance and will complete surveys.

Detailed description

Currently, natural history knowledge is limited for all PMM. The clinical phenotype and disease course may be distinct depending on the PMM genetic etiology, however variability between family members harboring the same genetic mutation is also well described. A major barrier to precise documentation of clinical progression has been the absence of meaningful and validated PMM-specific outcome measures. The long-term goal of these cumulative studies is to promote robust PMM clinical trial design and drug approval, as facilitated by natural history data and validation of PMM-specific objective outcome measures that enable accurate quantitation of symptoms. The overarching hypothesis is that deeper understanding of mitochondrial myopathy will promote meaningful clinical trial design. This study is approved under Children's Hospital of Philadelphia (CHOP), Institutional Review Board (IRB) protocol (#16-013364, PI Zolkipli) and is supported by a research infrastructure that includes physical therapists, biostatistician and bioinformatician for automated clinical data extraction from medical records.
