DNA has regions called exome and intron. Our genes, which provide the necessary code for protein production, are located in exome regions. For this reason, the WES test has an important place in the detection of mutations that can cause protein changes. In cases where a single gene analysis is not sufficient, analyzing different genes separately can be both costly and long-term. For this reason, genetic diseases can be diagnosed quickly, easily, and reliably by examining more than one gene at the same time.
