Providing insights into unclear health conditions through Mitochondrial testing
What is Mitochondrial testing?
Mitochondrial testing can help identify genetic changes causing mitochondrial disorders in either the nuclear DNA (nDNA) or mitochondrial DNA (mtDNA). Mitochondrial disorders may result from genetic changes in nDNA or mtDNA. Genetic changes in nDNA may be inherited from one or both parents. Genetic changes in mtDNA are only inherited from an individual’s mother. Changes in mtDNA might be new to the affected patient (de novo) or inherited from their mother who has a change in some mitochondria but not enough altered mtDNA to be affected herself.
Who should consider Mitochondrial testing?
Mitochondrial disorders can be identified at any point in a patient’s life. Multiple systems are often impacted by these disorders – the systems affected and severity of symptoms can vary greatly even between other affected family members.
Mitochondrial disorders might be caused by nDNA or mDNA changes . . .
Some of the most commonly affected organ systems:
If a mitochondrial disorder is suspected based on clinical symptoms or family history, additional genetic testing may be recommended to confirm the diagnosis.
Common Symptoms:
- Ataxia
- Stroke or stroke-like episodes
- Seizures
- Dementia
- Neuropathy
- Myopathy and cardiomyopathy
- Developmental delay
- Vision and hearing deficits
- Diabetes and other endocrine symptoms
- Gastrointestinal symptoms, such as pseudo-obstruction and dysmotility
- Laboratory abnormalities, such as elevated lactate: pyruvate ratio
