Summary Summary

CHARGE syndrome is a congenital condition (present from birth) that affects many areas of the body. CHARGE stands for coloboma, heart defect, atresia choanae (also known as choanal atresia), restricted growth and development, genital abnormality, and ear abnormality.^[1] Signs and symptoms vary among people with this condition; however, infants often have multiple life-threatening medical conditions.^[2] The diagnosis of CHARGE syndrome is based on a combination of major and minor characteristics. In more than half of all cases, mutations in the CHD7 gene cause CHARGE syndrome. When caused by a mutation in the CHD7 gene, it can be inherited in an autosomal dominant pattern; although most cases result from new (de novo) mutations in the gene and occur in people with no history of the condition in their family. Although there is no specific treatment or cure, there may be ways to manage the symptoms. A team of doctors is often needed to figure out the treatment options for each person.^[1]^[3]

Cause Cause

CHARGE syndrome is caused by mutations in the CHD7 gene in the majority of cases. Almost all mutations in affected individuals are de novo, which means they occur for the first time as new mutations and are not inherited from a parent. However, autosomal dominant inheritance with transmission from parent to child has been reported in rare cases.^[3]^[4]^[5]

The CHD7 gene provides instructions for making a protein that most likely regulates gene activity (expression). Most mutations in the CHD7 gene lead to the production of an abnormally short, nonfunctional CHD7 protein, which is thought to disrupt the regulation of gene expression. Changes in gene expression during embryonic development likely cause the signs and symptoms of CHARGE syndrome.

About one-third of individuals with CHARGE syndrome do not have an identified mutation in the CHD7 gene. The cause is unknown in these individuals, but researchers suspect that other genetic and/or environmental factors may be involved.^[5]

Last updated: 3/8/2013

Inheritance Inheritance

CHARGE syndrome is usually not inherited, typically occurring due to a new (de novo) gene mutation in the affected individual. However, rare familial cases inherited in an autosomal dominant manner have been described.

To our knowledge, all individuals who have a CHD7 mutation have some features of CHARGE syndrome (i.e. penetrance is 100%). In rare instances, one parent may have mild features, and the family history may appear to be negative because of failure to recognize the mild features of the condition.

The risk to the siblings of an affected individual depends on the genetic status of the individual's parents. If a parent of an affected child also has CHARGE syndrome, the risk for each sibling to inherit the condition is 50%. If neither parent is affected, the risk to each sibling of an affected child is estimated to be 1%-2%, most likely attributable to germline mosaicism. Prenatal diagnosis for pregnancies at increased risk is possible if the disease-causing CHD7 mutation has been identified in an affected family member.^[3]

Diagnosis Diagnosis

Genetic testing is available for CHARGE syndrome. The CHD7 gene is the only gene in which mutations are known to cause CHARGE syndrome. The CHD7 mutation detection rate when sequence analysis is performed is estimated to be 65%-70% for all typical and suspected cases combined.^[3]

GeneTests lists the names of laboratories that are performing clinical genetic testing for CHARGE syndrome. To view the contact information for these laboratories, click here. Please note that most of the laboratories listed through GeneTests do not accept direct contact from patients and their families. Therefore, if you are interested in learning more, you will need to work with a health care provider or a genetics professional.

Find a Specialist Find a Specialist

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.

Healthcare Resources

To find a medical professional who specializes in genetics, you can ask your doctor for a referral or you can search for one yourself. Online directories are provided by the American College of Medical Genetics and the National Society of Genetic Counselors. If you need additional help, contact a GARD Information Specialist. You can also learn more about genetic consultations from MedlinePlus Genetics.

Research Research

Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.

Patient Registry

A registry supports research by collecting of information about patients that share something in common, such as being diagnosed with CHARGE syndrome. The type of data collected can vary from registry to registry and is based on the goals and purpose of that registry. Some registries collect contact information while others collect more detailed medical information. Learn more about registries.

Registries for CHARGE syndrome:
United States Immunodeficiency Network (USIDENT) Registry

Organizations Organizations

Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer.
