Inherited Mitochondrial Disorders: a guide for families

Inherited mitochondrial disorders are genetic conditions that arise from mutations in the mitochondria, which are the cell's energy-producing structures. These disorders affect how the body generates energy, often leading to muscle weakness, neurological issues, and other health problems. Unlike most genetic traits, mitochondrial DNA is passed down only from the mother. Families may notice symptoms in childhood, but they can also emerge later. Diagnosis typically involves genetic testing, and management focuses on treating specific symptoms. Support from healthcare providers and patient advocacy groups can help families navigate these complex conditions effectively.
