The Congenital Disorders of Glycosylation (CDG) Clinic at Children's Hospital of Philadelphia (CHOP) provides diagnostic testing and comprehensive care for patients suspected of having congenital disorders of glycosylation (CDG).

CDGs are a large group of rare genetic disorders that cause a wide range of health problems and can affect every part of the body.

CDG interferes with the body’s ability to add sugar building blocks to proteins which our bodies need to function properly. There are more than 130 different forms of CDG, each with different genetic causes and each presenting its own unique set of health problems.

We help families by:

• Providing detailed information about your child’s specific CDG diagnosis
• Coordinating testing, treatment
• Sharing patient-specific recommendations
• Offering genetic counseling and access to research studies

Who we treat

The CDG Clinic is available to any patient – child or adult – who is suspected of having or been diagnosed with a congenital disorder of glycosylation (CDG). We welcome patients whether or not that have already been seen by a doctor within the CHOP system.
