Genetics professionals at SickKids and CHEO have developed several resources to help patients understand genetic testing. Below, you will find resources to help you understand genome-wide sequencing (GWS). GWS refers to whole exome sequencing (WES) and whole genome sequencing (WGS).
What is exome sequencing?
How can I get genome-wide sequencing?
There are many different types of genetic tests. Currently, only specialists with medical genetics expertise can order genome-wide sequencing (GWS) from GSO. If you are interested in GWS, please contact your health-care provider or genetics specialist to determine if GWS is appropriate for you.
You can also find a genetics clinic near you in Ontario. Please note that a consultation with a medical genetics specialist requires a referral from your doctor.”
How is genome-wide sequencing performed?
Once the patient or the patient’s parent has provided consent for testing, the patient will need to provide a blood sample. The patient’s health-care provider will also propose taking a sample from the patient’s biological parents to help with the analysis.
Testing will be performed at the SickKids Genome Diagnostic Laboratory and results will be returned to the patient’s health-care provider within 3 months on average.
