Expert Diagnosis and Care for Kids With Genetic Disorders

Nemours Children's pediatric geneticists help kids with complex conditions grow up healthy. We look for causes of developmental delays, physical differences, growth problems, learning issues and more. This information helps doctors and families make the best possible health decisions.

We use the latest technologies to study genes and how they’re involved in certain conditions. We’re experts in pediatric genetic disorders, including conditions that are present at birth, conditions that affect the brain, rare syndromes that have many symptoms at once, and many more.

Our team knows how genetic conditions can affect a child. We help doctors plan and manage care. We also tell you what to expect as your child grows and develops. Because some genetic disorders can be passed down through families, we may involve other family members too.

At Nemours, our team is actively researching new and improved genetic tests and treatments. This means we’re helping kids everywhere with certain diseases live better, and longer.
