GeneDx Launches New Online Offering for Families to Improve Accessibility of Exome Testing for Children with Global Developmental Delay, Intellectual Disability and Epilepsy

Business Wire

New offering integrates virtual clinicians to create a scalable channel to increase availability of GeneDx exome testing for eligible children facing specialty-care barriers

GAITHERSBURG, Md.--(BUSINESS WIRE)--
GeneDx (Nasdaq: WGS), the leader in rare disease diagnosis and improving health through the power of genomic data, today announced the launch of a new online offering designed to expand accessibility of exome testing across the U.S. at scale for pediatric patients with global developmental delay (GDD), intellectual disability (ID) or epilepsy.

Families can now initiate a genetic test directly from GeneDx.com, providing underserved children and families who face barriers to local specialty care with a faster path to clinician-guided exome testing. Exome testing is widely recognized as a first-tier tool for children with GDD, ID, and epilepsy, since up to 50% of causes are estimated to be genetic.^1,2

The new offering enables eligible families to access clinician-guided exome testing without first navigating lengthy specialty-care wait times, helping expand GeneDx’s reach to pediatric patients who may otherwise go untested. With over 450,000 children living with epilepsy in the U.S. and more than 1 million children in the U.S. with ID,³ the need for a precise and fast diagnosis is urgent. Across the U.S., wait times for an appointment with a geneticist continue to increase, with about 25% of pediatric patients waiting more than a year and about 50% waiting more than 6 months for a clinical genetics appointment.

In 2025, the American Academy of Pediatrics (AAP) updated its clinical guidance to recommend exome sequencing as a first-tier test for children with GDD or ID. For epilepsy and developmental delay, earlier diagnosis can guide treatment decisions, reduce unnecessary testing, and improve long-term management.

“For too many families, the path to answers is defined by delays, barriers, and a system that isn’t built for the realities they face,” said Katherine Stueland, CEO of GeneDx. “By making exome testing simpler and easier to access, we can reach more children who need answers and move closer to a healthcare system that delivers on the promise of precision medicine.”

The new offering enables families to initiate genetic testing through a simplified, digital experience on the GeneDx website – connecting them directly with licensed healthcare providers who can review medical information, order testing, and deliver results without requiring traditional in-person visits. Designed to complement a child’s pediatrician, neurologist, or specialist, the offering expands access beyond traditional referral channels while supporting coordinated, ongoing care.

“Exome testing can provide critical answers for children with developmental delay, intellectual disability and epilepsy, but too many families still face barriers to timely access,” said Linda Genen, M.D., MPH, Chief Medical Officer of GeneDx. “This offering removes friction by creating a clinically guided path to appropriate testing that complements a child’s existing care and helps families get answers sooner.”

By removing friction and enabling faster access to expert-guided testing, this new offering advances GeneDx’s commitment to expanding access to precision medicine and delivering earlier, more accurate diagnoses. The offering is now available to eligible pediatric patients across the United States, subject to provider availability, clinical appropriateness, and applicable state requirements.
