One manifestation of cytochrome oxidase deficiency in humans is severe muscle weakness?

Cytochrome oxidase deficiency, a rare mitochondrial disorder, disrupts the electron transport chain, leading to impaired ATP production. This energy deficit primarily affects high-energy-demand tissues, such as muscles, resulting in severe muscle weakness and fatigue. Other symptoms may include neurological issues and exercise intolerance, reflecting the critical role of oxidative phosphorylation in cellular energy metabolism. Early diagnosis and management are crucial for improving quality of life in affected individuals.
