Division of Human Genetics
Whether your child has been diagnosed with a genetic disorder – or is suspected of having one – Children’s Hospital of Philadelphia (CHOP) is here to help.
Our Division of Human Genetics provides comprehensive diagnostic testing, genetic counseling, individualized treatment and ongoing care management for children with a wide variety of genetic diseases and pediatric disorders.
We offer the most complete array of human genetics services in the Delaware Valley for children and their families. Our division includes a Clinical Genetics section and two full-service, state-of-the-art testing laboratories.
We specialize in finding answers for families facing complex and hard-to-diagnose conditions. We work with researchers to improve testing, treatment options and outcomes. And we remain committed to better understanding the genetic basis for all pediatric disorders.
