Comparing whole genome sequencing and exome sequencing

Introduction Next-generation DNA sequencing empowers scientists to identify genetic variations associated with human disease at higher resolution and greater sensitivity than previously possible. Two approaches are commonly employed -exome sequencing and whole genome sequencing. Exome sequencing targets protein-coding regions comprising approximately 1% of the human genome, while whole genome sequencing uses an unbiased approach to investigate the majority of the human genome, including a comprehensive survey of coding and non-coding regions.
