Third Quarter 2025 and Recent Business Highlights

Strategic Expansion and Market Leadership

Introduced GeneDx Infinity™, the largest rare disease dataset, which serves as the foundation for rare disease insights and powers GeneDx's ExomeDx™ and GenomeDx™.
Exhibited at the American Academy of Pediatrics (AAP) Annual Meeting, educating pediatricians about the updated AAP guidance recommending exome and genome sequencing as first-tier tests for children with global developmental delay or intellectual disability.
Expanded coverage of whole genome sequencing with California Medicaid (Medi-Cal), opening access to testing in the nation's most populous state and bringing the number of states covering exome or genome testing in the outpatient setting to 36.
Announced the Autism Partnership Program in partnership with Jaguar Gene Therapy, expanding access to exome and genome testing for patients suspected of having SHANK3-related autism spectrum disorder (ASD) and Phelan-McDermid syndrome - the leading single-gene cause of ASD.
Appointed Lisa Gurry as Chief Business Officer and Dr. Mimi Lee as Chief Precision Medicine Officer to accelerate precision medicine across policymakers, health systems, biopharmaceutical companies, advocacy groups, and payers to help more families with the power of data, AI, and clinical expertise.
Appointed Dr. Thomas Fuchs, MD, PhD, to the board of directors, contributing his background at the intersection of AI and human health to support GeneDx's business and mission.

Innovation & Clinical Leadership

Granted FDA Breakthrough Device Designation for GeneDx ExomeDx™ and GenomeDx™ associated with causes of life-threatening diseases or genetic disorders to aid in diagnosis of symptomatic patients, underscoring GeneDx's leadership in genomic medicine and critical role in delivering fast, accurate answers for patients with rare diseases.
Expanded leadership in genomic newborn screening through participation in key programs, including:
- Announced participation in the nation's first multi-state genomic newborn screening initiative, BEACONS (Building Evidence and Collaboration for GenOmics in Nationwide Newborn Screening), which was launched with a $14.4 million NIH award to enroll up to 30,000 newborns in as many as 10 states over the next three years.
- Announced a partnership with Florida's Sunshine Genetics Network to launch the nation's first state-backed genomic newborn screening program and offer whole genome sequencing for newborns at select academic medical centers and hospitals, providing families and clinicians the opportunity for early detection and diagnosis of rare diseases.
Added to the company's 1,000+ publications and growing by showcasing pioneering research at the American Society of Human Genetics (ASHG) Annual Meeting including:
- AI and machine learning approaches in rare disease diagnosis: In a study of over 250,000 exome and genome trios, GeneDx's machine learning approach addresses challenges of identifying de novo variants with high accuracy and throughput, enabling greater efficiency and scalability.
- The genetic causes of autism: In a study of over 62,000 individuals affected with autism, researchers highlight a core set of over 250 genes associated with autism and found moderate genetic correlations between autism and schizophrenia, epilepsy, and bipolar disorder.
- Genomic newborn screening (gNBS): Updated results from the GUARDIAN study reports data from 15,000 newborns and demonstrates high enrollment rates, positive parental experiences, and meaningful follow-up outcomes – reinforcing the value of gNBS in accelerating time to diagnosis.
- Clinical validation for long read sequencing: Long-read sequencing approaches demonstrate strong potential to improve clinical diagnostics, accurately detecting repeat expansions and resolving difficult-to-sequence regions.
Showcased leadership in genomic newborn screening at the International Consortium of Newborn Sequencing (ICoNS), with data presented on GeneDx's more than 22,000 newborns sequenced.
