What is Mitochondrial Genome Sequencing (mtDNA)?
Our DNA is made up of parts that we inherit from both parents - this DNA is stored in a region of the cell called the nucleus (and called nuclear DNA or nDNA). We also have a second, separate DNA that we inherit only from our mothers and it resides in the mitochondria. This is called mitochondrial DNA (mtDNA). This mtDNA is responsible for things like the generation of energy sources for our cells.
A certain number of diseases are caused by changes in mtDNA. Because the structure of mtDNA is different from nDNA, different sequencing methods are used by Discovery DNA to diagnose mitochondrial diseases. Therefore, this mtDNA test must be run separately to get the yields that we look for to provide medically actionable results.
When should I order a mtDNA test?
This test should be ordered if there is a good idea that your symptoms or condition is based on the mitochondrial genome. Please refer to our recommendations section for further guidance.
