What is the Seattle Children’s 22q Clinic?
Seattle Children’s 22q Clinic cares for children who have differences in a part of chromosome 22 called the q11.2 region.
Our 22q Clinic brings together experts from many departments to care for children who have 22q11.2-related disorders. These differences can cause a wide variety of problems, from mild to severe.
Why choose the 22q Clinic at Seattle Children’s?
Most families have never heard of 22q11.2-related disorders before their child is diagnosed. Our 22q Clinic has been diagnosing these conditions and helping families care for their children since 2006. We are the only multidisciplinary clinic for children with 22q11.2-related conditions in the 5-state region that includes Washington, Alaska, Montana, Idaho and Wyoming.
At the 22q Clinic, a team experienced with these conditions will evaluate your child. We create a personalized care plan for your child and bring in other experts to meet your child’s specific needs.
We work to understand the total picture of your child’s health. Our goals are to diagnose and care for each problem that affects your child.
How can the 22q Clinic help my family?
We welcome expectant parents who have questions after testing during pregnancy or because of a family history of these conditions.
If prenatal testing shows that your baby may have a 22q11.2-related disorder, our medical geneticist and genetic counselor can help you understand the test results and suggest other tests if needed.
Tests may be done on samples from:
- An expectant mother’s blood, which includes DNA from the placenta. This is called noninvasive prenatal screening (NIPS).
- Amniotic fluid that surrounds and protects a baby in the womb (amniocentesis).
- The placenta, through a test called chorionic villus sampling (CVS).
The tests can show if there are changes that might mean a 22q11.2-related disorder. But tests cannot tell how much these genetic changes will affect your baby. We may suggest more tests, such as a fetal heart scan (fetal echocardiogram) to look for heart defects.
Your doctor will examine your child and look for the differences that are linked with 22q11.2-related disorders. Since the symptoms of the conditions differ from child to child, a careful exam is important.
We may test your child’s blood to look for genetic changes to confirm a 22q11.2-related disorder.
Your child may need other tests or procedures to learn more about their exact condition. For example, an ultrasound picture of their heart (echocardiogram) can show if they have any heart problems.
Our clinic can easily form a team with the right experts to care for your child’s specific needs. Our experienced team has specialists in 10 different fields.
Your child can receive much of their care in the same place at the same time. If your child needs to be checked by other departments at Seattle Children’s, we coordinate appointments to reduce the number of clinic visits.
We work together, and with you and your family’s doctor, to care for your child.
It is often helpful to connect with other families whose child has a 22q11.2-related disorder. Our social worker helps you get the support you need. We will also put you in touch with resources in your community.
Our clinic takes part in events to help families meet each other and to raise awareness of these conditions.
Who is on the 22q Clinic team?
A pediatrician and nurse experienced in caring for children with craniofacial conditions will work closely with your family.
Because of the high rates of problems in the following areas, your child’s team is likely to include providers with special training in:
- Genetic counseling
- Medical genetics
- Social work
- Speech and language pathology
These providers are all part of our coordinated 22q Clinic team.
Depending on your child’s needs, they may also receive care from other Seattle Children’s specialists for problems related to their bones, eyes, gastrointestinal system, heart, endocrine system, immune system, kidneys or mental health.
As your child nears age 21, we work with the transition care team at the University of Washington to help your child move from child-centered to adult-centered medical care.
What to Expect at Your First Visit
During your first appointment at the 22q Clinic, you will meet a pediatrician or pediatric geneticist, in addition to a genetic counselor with expertise in 22q11.2-related disorders. They will determine which specialists should be on your child’s care team, based on your child’s age and health needs.
We will review any genetic test results you have and let you know if additional testing is needed.
Families traveling from outside the Puget Sound area may want to have a first visit that combines reviewing genetic tests and meeting the experts your child is likely to need. That type of visit may take longer to schedule.
