Helping Families with the Specialized Care They Need

Our team has helped countless families in need of care for their children, like Stephen Monaco, who was diagnosed with isovaleric acidemia at age 3 1/2.

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. We aim 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.

With more than 8,500 visits annually and 12 physicians, Children’s National Hospital is home to the largest clinical genetics program in the United States.

National Organization for Rare Disorders logoWe have received national recognition for our efforts, as we were the first entity to be named a Center of Excellence by the National Organization for Rare Disorders.

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.

Your child's appointment may be available as a telehealth visit. Please call the Bear Line at 1-888-884-BEAR (2327) to schedule and learn more.

Our Rare Disease Institute offers a virtual genetics clinic, allowing patients to be evaluated from home. Along with in-person visits, this enables us to optimize and tailor care for every child and family. Telehealth decreases wait times and allows simple issues to be addressed quickly. Among the benefits of video visits are: 

  • Increased frequency of visits for high-risk patients
  • Patients with autism can be seen in their home setting
  • Dietitians can view inside the home refrigerator
  • Multiple providers at various locations can share screens and coordinate video visits
  • Can be combined with in-person visits when deemed appropriate
  • Saves clinic slots for patients that need to be seen in person

In addition, video visits remove barriers to care, such as: 

  • Transportation
  • Child care for other children
  • Fear of exposure to illness for at-risk patients in a hospital setting
  • Missed work

To inquire about our Telehealth Program, email Monisha Kisling, CGC, one of our genetic counselors. 

Conditions We Care For and Services We Provide

Leaders in Diagnosing and Treating Rare Disease

Listen to Marshall Summar, M.D., speak about the importance of the CNRDI.  

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.

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.   

Children’s National also provides educational outreach to community physicians, schools and families through lectures, seminars and parent support groups.

Genetic testing is not currently covered by all health care 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.
