Mitochondrial diseases are genetic disorders that affect the mitochondria, the energy-producing structures found within cells.

These diseases are caused by mitochondrial or nuclear DNA mutations that impair mitochondrial function.

Mitochondrial disorders can affect multiple organs and systems, resulting in a variety of symptoms.

Some of the most common symptoms are fatigue, muscle weakness, developmental delays, and neurological issues.

Genetic testing and a thorough examination of clinical symptoms are frequently used to diagnose mitochondrial diseases.

Treatment options are limited, with the emphasis on symptom relief and quality of life.

mitochondrial DNA is present in the egg, mitochondrial diseases can be inherited maternally.

The severity of mitochondrial disorders varies greatly among individuals, even within the same family.
