13 GeneDx offers leading exome and genome products • Genome sequencing – Analyzes the entirety of an individual’s DNA, which is known as the genome. The genome includes ~20,000 genes. • Exome sequencing – Analyzes the protein coding regions of the ~20,000 genes in an individual’s genome, which is known as the exome. The exome is thought to contain a majority of disease-causing genetic variants. Translating complex genomic data into definitive diagnoses for patients

Changing the perception of exome and genome sequencing GeneDx has spent over a decade solving for limitations of the past and differentiating our products Then GeneDx Now “I can get results in days to weeks”“These tests take months to get results” “These tests are wildly expensive” “Tests are affordable and widely covered” “Results are confusing and filled with useless information” “My patient can get a definitive diagnosis” Turnaround time Cost Interpretation 14

Medical practice guidelines recommend exome and genome sequencing for patients ACMG Practice Guideline1: “Strong recommendation based on the available evidence to support the use of ES/GS as either a first- (or second-) line test in patients …. ES/ GS demonstrates clinical utility for the patients and their families with limited evidence for negative outcomes and the ever-increasing emerging evidence of therapeutic benefit.” NSGC Guideline2: “Recommending Exome Sequencing as a First-Tier Genetic Test for Unexplained Epilepsies” 22 American Epilepsy Society: “Exome or genome sequencing are favored for most scenarios, as they are more likely to provide a diagnosis.” 1.
