Exome sequencing is a technique used in genetics and genomics research that involves sequencing the exons, or protein-coding regions, of the genome. This method focuses on the subset of the genome that is most likely to contain disease-causing mutations, making it a cost-effective and efficient way to identify genetic variations associated with human diseases. Exome sequencing can be used to diagnose genetic disorders, study the genetic basis of complex diseases, and identify potential targets for personalized medicine. By analyzing the exome, researchers can gain valuable insights into the genetic factors underlying various health conditions and develop new strategies for disease prevention and treatment.
