Williams Syndrome Clinic
Caring for Children and Adults With Williams Syndrome
Williams Syndrome Clinic at Nationwide Children's Hospital
The Williams Syndrome Clinic at Nationwide Children's uses an interdisciplinary model to bring together experts in a host of specialties to provide unmatched care for children and adults with Williams syndrome. Our care teams include a central physician (usually a geneticist or developmental pediatrician) and specialists (cardiologist, psychologist, endocrinologist, nephrologist, gastroenterologist, therapy services and more) chosen to meet each person's health care needs. Because the team works together, each individual's care plan includes shared input from all involved disciplines and are optimized to incorporate the most up to date research findings. Since 2007, families from around the U.S. and around the world have traveled to our clinic for care.
Our team has published dozens of articles covering best practices for Williams syndrome. The Nationwide Children’s Williams Syndrome Clinic is a member of the U.S. Williams Syndrome Clinical Consortium and the Collaborative Registry for Williams Syndrome (CReWS).
Our Services
The Williams Syndrome Clinic offers the right fit for your family. Services are individualized and may include focused consultation regarding a limited number of medical problems or a comprehensive second look evaluation from a team of specialists with special attention to the unique medical, developmental and behavioral problems experienced by people with Williams syndrome. We also see children and adults with Williams syndrome for ongoing health maintenance. Laboratory and radiologic assessments are arranged as needed.
Our team works closely with many pediatric teams, including:
- Anesthesiology and Pain Medicine
- Audiology
- Cardiology
- Clinical Therapies (including speech, occupational and physical therapy)
- Developmental and Behavioral Pediatrics
- Endocrinology
The team also collaborates with adult providers in many of the same specialties. Your team will help you transition to adult providers to ensure continuity of care from youth to adulthood.
Services may be covered by insurance. Our team will work with you to understand resources that may be available to you. To expedite insurance coverage, we recommend a referral be sent to the clinic by the individual’s primary care physician. It is also recommended that the family contact their insurance company prior to visiting the clinic. Travel and housing information is available for families visiting the clinic over more than one day.

Williams Syndrome Clinical Research
Help Us Learn More About Williams Syndrome and SVAS
The Williams syndrome (WS) and Supravalvar Aortic Stenosis (SVAS), DNA and Tissue Study is a research study that aims to learn more about genetic differences that contribute to outcomes seen in people with these rare conditions. Questions studied include how the genes work and whether there are other changes in the genome that impact the severity of certain features like cardiovascular disease. Involvement includes contributing a DNA sample and answering online questionnaires. Participants may also choose to donate tissue from a surgery or share their medical records to help investigators learn more about how changes in genes affect the way a person cells work.
Eligible participants include individuals with WS, SVAS, or similar conditions, as well as unaffected family members aged 0-85 years.
Talk to your William’s syndrome clinic team for more information.
Collaborative Registry for Williams Syndrome (CReWS)
The Collaborative Registry for Williams Syndrome (CReWS) is made by and belongs to the Williams Syndrome Association. It collects information about people with Williams syndrome (WS) to help us learn more about the condition and find better treatments.
CReWS gathers and organizes details and medical records of people with WS. It also helps connect families with doctors and scientists who are studying the condition.
Request an Appointment
To request an appointment, we will need an official referral from your primary care doctor or referring physician faxed to either (614) 722-4000 or (614) 938-8555.
A Referral Was Sent: Now What?
We will send a clinic intake form, complete a brief questionnaire, collect demographic information and answer any initial questions about clinic during the intake call and will ask insurance information. We will then contact the clinic nurse, who will schedule the appointment.

"The Williams Syndrome Clinic at Nationwide Children’s provides an invaluable resource to us as the parents of an eight year old daughter with Williams Syndrome. While our daughter receives various private therapies and sees her pediatrician on a regular basis, having a team of professionals at Nationwide Children’s to rely upon who have a wealth of experience in dealing with the many complexities of Williams Syndrome has been tremendously helpful. We always come away from our visits to the Clinic with information that is beneficial to the continued well-being and development of our daughter."
