What is a whole exome test?
Whole Exome Sequencing (WES) is a comprehensive genetic test that identifies changes in a patient’s DNA that are causative or related to their medical concerns. By focusing on the entire protein-coding regions of the genome – the exome – WES offers you the coverage you need to diagnose patients rapidly and reliably.
