Perhaps the most widely used targeted sequencing method is exome sequencing. The exome (the protein-coding region of the human genome) represents less than 2% of the genome, but contains ~85% of known disease-related variants,1 making whole-exome sequencing a cost-effective alternative to whole-genome sequencing.
Exome sequencing using exome enrichment can efficiently identify coding variants across a wide range of applications, including population genetics, genetic disease, and cancer studies.
Exome sequencing is a cost-effective approach when whole-genome sequencing is not practical or necessary. Sequencing only the coding regions of the genome enables researchers to focus their resources on the genes most likely to affect phenotype, and offers an accessible combination of turnaround time and price.
Exome sequencing detects variants in coding exons, with the capability to expand targeted content to include untranslated regions (UTRs) and microRNA for a more comprehensive view of gene regulation. DNA libraries can be prepared in as little as 1 day and require only 4–5 Gb of sequencing per exome.
