GAITHERSBURG, Md.--(BUSINESS WIRE)--GeneDx (Nasdaq: WGS), a leader in delivering improved health outcomes through genomic insights, announces the American Academy of Pediatrics (AAP) issued updated guidance to now recommend exome and genome sequencing as first-tier tests for children with global developmental delay (GDD) or intellectual disability (ID) in most circumstances because of superior diagnostic yield and higher cost-effectiveness if pursued earlier in the diagnostic process 2. For more than 60,000 pediatricians, this milestone marks a turning point in pediatric healthcare, ushering in earlier diagnosis, interventions, and improved outcomes for millions of children.

'The AAP's updated guidance is a long-overdue validation of what many of us have known – earlier access to genomic testing leads to faster, more accurate diagnoses and better outcomes – and represents an important milestone in bringing genomics to the front line of pediatric medicine as we seek to protect children from unnecessary disease progression,' said Katherine Stueland, President and CEO of GeneDx. 'Exome and genome testing are no longer tests of last resort; they are now the first step, and there is no one better equipped than GeneDx to support pediatricians through this next chapter. We're ready to slash the average five-year diagnostic odyssey to a fraction of that time, drive down healthcare costs, and, most importantly, change children's lives sooner. Having driven innovation and advanced patient care through genomic testing, working in partnership with geneticists and pediatric specialists, GeneDx is best positioned to empower general pediatricians to take a leading role in early diagnosis and precision medicine.'
The new diagnostic approach underscores the growing recognition that pediatricians are the front line of genetic medicine and marks a major advancement by equipping these clinicians with actionable genomic insights to accelerate targeted treatments and end the burdensome diagnostic waiting period faced by too many families today. Previous guidance from AAP 3 , published in 2014, recommended the use of narrow testing such as Chromosomal Microarray Analysis (CMA) and FMR1, both of which can be considered antiquated recommendations for these patient populations considering the advancements made with exome and genome testing, including the superior diagnostic yield, cost-effectiveness and speed to diagnosis.
GeneDx is the leader in advancing genomic technologies, providing clinicians and patients with access to comprehensive exome and genome testing. With unparalleled expertise from sequencing more than 800,000 exomes and genomes – alongside millions of phenotypic data points – GeneDx has assembled one of the largest, rare disease datasets. GeneDx's standard exome and genome results are available in as little as three weeks, and insurance coverage for this testing continues to expand across the country, supported by coverage from major commercial payors and Medicaid programs.
"Given general pediatricians depend on clinical guidance to provide the best possible care for our patients, this updated report will empower pediatricians to offer families the most current, evidence-based genetic testing — helping to shorten the often long and difficult diagnostic journey," said Dr. Deborah Ondrasik, General Pediatrician, Southcoast Health. "I'm thrilled to see the AAP update these recommendations to reflect just how far genetics have come in the past decade. This is a meaningful step forward for our patients and their families."
With its recently launched brand campaign, Diagnosis is Power, GeneDx is educating clinicians and parents on the need for earlier genetic testing to accelerate answers and improve outcomes for more patients and families. Core to its mission, GeneDx believes in the power of diagnosis and envisions a world where any genetic disorder is diagnosed quickly to prevent disease progression and ensure long and healthy lives for all.
