Genome Sequencing

CLIA/CAP Whole Exome Sequencing

WES is one of the most comprehensive tools available for detecting rare diseases and associated variants in an individual’s DNA. Whole Exome includes all the protein coding regions in the human genome (approximately 20,000 genes), which is believed to cover >85% of known and potential disease-causing genetic variants.

Who Benefits from WES?

  • A genetically heterogeneous disorder
  • A long list of differential diagnoses
  • An atypical presentation of a genetic disorder
  • A suspected genetic diagnosis, but previous genetic testing has been negative
  • A need for a cost-effective alternative to whole genome sequencing
