Mitochondrial Genome Sequencing

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 DNA that we inherit only from our mothers because it is in the mitochondria. This is called mitochondrial DNA (mtDNA). 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 Discovery DNA is used to.

Discovery DNA can test both the nuclear and mitochondrial DNA from the same sample. While no sequencing technology can detect every type of genetic disease, doing both nuclear and mitochondrial DNA together produces a higher yield overall. At Discovery DNA, our focus is on medically actionable results. A Genetic Counsellor will review the results with you and if there is a medical condition that requires the attention of a Doctor, then a Doctor will also review the results with you and provide information that will help your family doctor or specialist know what steps to do next to look after your health. We provide personal care to address your needs for genetic testing.


Results are typically ready within 14 business days, once received in the laboratory. Discovery DNA makes no guarantee as to when test results will be available, as demand may exceed laboratory capacity.  We reserve the right to limit quantity of orders purchased.  Cosent forms must be filled out, emailed and returned to us prior to shipping of kits.  Email consent forms to the following email address:

Mitochondrial Genome Sequencing


    Thanks for purchasing, or considering to purchase, a  Mitochondrial Genome Sequencing test from our website We appreciate your business during these stressful times.

    We take pride in performing the adequate quality control measures and taking the steps necessary to ensure that our lab’s protocols actions and procedures are trackable and ultimately provide you with a test result that you can trust.

    The amount of money back provided from refunds is different depending on the conditions of your order. We invite you to read the conditions explained in more detail below, in order to see the condition that applies to your situation, while following the correct procedure.

    1. If you cancel your order before we ship your sample collection kit: If you request a refund after placing your order, but before our Sample Coordinator ships you your sample collection kit, we will provide you with a full refund less a small service charge.

    2. If you cancel your order after we ship you your sample collection kit: If you request a refund after your sample kit is shipped to you, OR after you ship back the collection kit, we will provide you with a full refund less shipping and collection kit costs, and a small service charge
