Primary Mitochondrial Disorders Overview

Primary mitochondrial disorders, as detailed in this GeneReview, encompass genetic conditions affecting the mitochondrial respiratory chain due to mtDNA and nDNA mutations. These mutations disrupt aerobic metabolism, resulting in diverse clinical symptoms like myopathy, neuropathy, cardiomyopathy, and diabetes. Inheritance patterns and heteroplasmy thresholds are critical for understanding symptom presentation. The

Mitochondrial Dysfunction as an Underlying Cause of Skeletal Muscle Disorders

This systematic review discusses how mitochondrial dysfunction is a primary contributor to skeletal muscle disorders, driven by impaired oxidative phosphorylation, mtDNA mutations, calcium imbalance, defective mitophagy, and abnormalities in mitochondrial dynamics. These disruptions lead to decreased energy production, muscle degeneration, and cellular stress. The review emphasizes the need for targeted
