Caring for Children With Phelan-McDermid Syndrome, From Diagnosis Forward
Phelan-McDermid syndrome is a rare genetic condition caused by changes in the SHANK3 gene on chromosome 22q13. It affects brain development and can impact learning, communication, behavior and physical health. Symptoms can vary widely, which often leaves families feeling unsure about what to expect.
At the Phelan-McDermid Syndrome Clinic at Cincinnati Children’s, we help families understand this complex condition and what it may mean over time. Our team provides clear guidance, coordinated care, and ongoing support, so families never have to navigate Phelan-McDermid syndrome alone.
