Advancing Care Through Pediatric Genetic Discovery 

The Molecular Diagnostic Laboratory at Nemours Children's in Delaware Valley brings advanced genetic techniques to the understanding of childhood disorders. Our CLIA-certified facility provides comprehensive molecular testing for inherited conditions, with specialized expertise in muscular dystrophy, spinal muscular atrophy, and blood disorders like sickle cell disease and thalassemia. 

We use molecular technologies such as Sanger sequencing, multiplex ligation-dependent PCR amplification (MLPA), and real-time PCR to conduct sophisticated DNA analyses. These tools help us identify the specific genetic changes involved in various inherited conditions. This enables physicians to make accurate diagnoses and targeted treatment plans.

Beyond clinical diagnostics, our lab serves as a research partner, working closely with clinicians, researchers, and academic institutions to advance our understanding of pediatric genetic conditions. 

Through collaborative initiatives, we're shaping the future of pediatric medicine. Our research partnerships contribute to groundbreaking discoveries that advance treatment options and bring hope to children with genetic disorders.
