For Patients

What is Horizon Carrier Screening?

The Horizon carrier screen is a simple test that looks at your genes to see if you are a carrier for specific autosomal recessive and X-linked genetic conditions. It is common for people to be carriers of at least one genetic condition. Carriers are usually healthy; however, they have a risk of passing on a genetic condition to their children. Horizon can provide valuable information to you about your carrier status before or during pregnancy.

For providers

What's Horizon?

Horizon™ screens your patients to determine their carrier status for up to 274 autosomal recessive and X-linked genetic conditions. Many of these conditions are early onset, while some conditions develop later in life. Conditions have been carefully selected to be appropriate for your unique mix of patients.

Diseases We Screen

Horizon screens for up to 274 autosomal recessive and X-linked genetic conditions. Patients can be screened for all of these conditions or a select few based on their ethnic background and their physician’s recommendation. 

Common Questions

Who should have Horizon carrier screening?

Anyone who is pregnant or planning a pregnancy can have Horizon carrier screening. Egg or sperm donors may also have carrier screening. Ask your doctor or genetic counselor if Horizon carrier screening is right for you. Please note this testing is not available to minors in some cases. Horizon carrier screening for X-linked disorders is limited to female patients.  

When should I have Horizon carrier screening?

Horizon can be done before or during pregnancy. Some people may want to have more information about the chance to have a baby with a genetic disease before pregnancy. Others may have screening during a pregnancy.

What are the benefits of having Horizon carrier screening?

Horizon can help you and your partner learn about the chance to have a child with a genetic disease before or during pregnancy. Many people do not know they are a carrier for an inherited genetic disease until they have an affected child. While there is no test that can screen for all possible genetic diseases or birth defects, genetic carrier screening can give you information to make reproductive choices that are right for you and your family.   

Do I need to have carrier screening more than once?

Carrier screening is usually done once as your carrier status for a specific condition typically does not change. Depending on what you have been screened for in the past, your doctor or genetic counselor may recommend additional carrier screening for more conditions. So, it is possible to have carrier screening more than once. Ask your doctor or genetic counselor to find out what’s best for you.
