Note: As a value-add, this test includes pharmacogenomic analysis (PGX) and mitochondrial genome analysis (mtDNA), unless you choose to opt out.


What is a whole exome sequencing (WES) test?

A whole exome sequencing (WES) test analyzes all of someone's DNA that is responsible for making proteins. By doing this, we look at approximately 20,000 genes and see if there are any changes that could have any clinically significant effects. 


During your pre-test consultation, we will ask you what kind of things you are concerned about (e.g., chronic pain, seizures, or other widespread symptoms), and use that information to look for any gene variants that could potentially be affecting those concerns. We will then report the results to you in a post-test consultation, and can provide a letter to your doctor to help inform the next steps.


When should I order a WES test?

If it is not quite clear what the cause of a patient's symptoms is, or if multiple gene panels are being considered to find a diagnosis, a WES test can provide a more cost and time efficient way of finding out the gene variation responsible for a patient's conditions and/or symptoms.
