Children’s National Rare Disease Institute (CNRDI) is a first-of-its-kind center focused exclusively on advancing the care and treatment of children and adults with rare genetic diseases. Designated by the National Organization for Rare Disorders
(NORD) as its first Center of Excellence for Clinical Care for Rare Diseases, the CNRDI aims to provide a medical home for patients and families seeking the most advanced care and expertise for rare genetic conditions that remain largely unknown to the general medical community.
Genetics and Metabolism at Children's National
With more than 8,500 visits annually and 12 physicians, Children’s National Health System is the largest clinical genetics program in the United States.
Our division coordinates the multidisciplinary care of children with genetic, metabolic and undiagnosed disorders in collaboration with primary care physicians and specialists from other divisions at Children’s National. Additionally, every geneticist at Children’s National works in concert with a genetic counselor to manage both the clinical and practical aspects of treatment. The research interests of our practitioners ensure the most timely and thoughtful care for our patients.
Our team of world-renowned medical experts, metabolic dietitians, nurse practitioners and genetic counselors offer care for your child’s physical needs, while our social workers, child life specialists and chaplaincy services staff offer support for your child and your family’s emotional, spiritual and mental health needs.
Our Inherited Metabolic Disorders Program is one of the largest in the country with more than 600 active patients. These disorders are rare among the general population and may be misdiagnosed, as symptoms are often similar to other conditions. Our program provides diagnostic testing, evaluation and management for patients with inborn errors of metabolism, as well as definitive testing and treatment for patients identified by newborn metabolic screenings. If your child is diagnosed with one of these disorders, the program offers a comprehensive specialized team that coordinates all aspects of your child’s care, including the services of metabolic dietitians for patients who must follow a special metabolic diet.

Leaders in Diagnosing and Treating Rare Disease
Children’s National is nationally and internationally acknowledged as a leader in treating metabolic diseases, urea cycle disorders, genetic syndromes and lysosomal storage diseases. The well-rounded nature of the clinical team also makes Children’s National a noted destination for treatment of rare and ultra-rare metabolic disorders, such as NAGS and propionic acidemia.
Genetic Counseling and Family Services
Our genetic counseling team is committed to providing compassionate support for patients and their families. We provide genetic counseling services for families with a known genetic disorder and recurrence risk counseling for parents of a child with an inherited condition.
Our genetic counselors provide information on family planning options, explain the testing options available to you and help coordinate referrals for related specialists at Children’s National. We see patients through self-referral or with referral from a primary care physician or another subspecialty clinic within Children’s National.
We also provide in-depth counseling for carrier screening results.

Genetic testing is not currently covered by all healthcare plans. As our team works with your family, we will discuss testing options and attempt to optimize your testing plan in line with your insurance guidelines. Contacting your insurance before your visit to determine their testing guidelines has been helpful for some families to direct our conversations.
You will be seen by both a geneticist and a genetic counselor, both of whom will submit a bill to your insurance provider. If you have health insurance that requires a referral and/or authorization for geneticist or genetic counseling services, please bring your referral to your appointment. If you are unsure if you need a referral, please contact your primary care physician or health insurance provider.
