whole exome sequencing

(hole EK-some SEE-kwen-sing)
A laboratory method that is used to learn the exact order of all the building blocks that make up the pieces of a person’s DNA that contain information for making proteins. These pieces, called exons, are thought to make up about 1% of a person’s genome (complete set of DNA). Whole exome sequencing is used to find mutations (changes) in genes that may cause diseases, such as cancer. Also called WES and WXS.
