About this trial

This is a longitudinal study in a cohort of patients with a genetic diagnosis of Primary Mitochondrial Myopathy to describe the natural history of the disease and identify clinical, biochemical, molecular, and radiological variables that allow evaluation of the severity and progression of the disease and may be useful in future clinical trials.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Muscle symptoms: exercise intolerance and fatigue, myalgia, recurrent rhabdomyolysis, chronic progressive external ophthalmoplegia and/or muscular weakness

Primary mtDNA mutation or pathogenic mutations in nDNA, especially in genes related to mtDNA maintenance such as TK2, POLG, TWNK and RRM2B, among others.
