Your Question

My mother-in-law has been diagnosed with Gardner syndrome. How is this syndrome inherited? Is there a genetic test to find out if my wife, and eventually our children are affected with Gardner syndrome?

Our Answer

We have identified the following information that we hope you find helpful. If you still have questions, please contact us.

How is Gardner syndrome inherited?

Gardner syndrome is inherited in an autosomal dominant manner.[1] This means that to be affected, a person only needs a change (mutation) in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. A person with Gardner syndrome has a 50% chance with each pregnancy of passing along the altered gene to his or her child.

Is genetic testing available for Gardner syndrome?

Yes, genetic testing is available for APC, the gene known to cause Gardner syndrome. Carrier testing for at-risk relatives and prenatal testing are possible if the disease-causing mutation in the family is known. Because colon screening for those at risk for Gardner syndrome begins as early as age ten years, genetic testing is generally offered to children by this age.[1]

The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.

How can I find a genetics professional in my area?

Genetics clinics are a source of information for individuals and families regarding genetic conditions, treatment, inheritance, and genetic risks to other family members. More information about genetic consultations is available from Genetics Home Reference. To find a genetics clinic, we recommend that you contact your primary healthcare provider for a referral.
