Horizon: A Comprehensive Genetic Carrier Screening

Horizon is a genetic carrier screening test for prospective parents that helps assess the risk of passing on serious genetic conditions to their child. It can be done before or during pregnancy. Most carriers are healthy with no family history but can still pass on a condition. Horizon identifies whether you carry a gene variant that could affect your child.

Horizon Tests Offered:

Horizon 4 panel (CF, SMA, Fragile X, DMD)
Horizon 27 panel (Pan-ethnic Standard)
Horizon 274 panel (Pan-ethnic Extended)
Horizon 613 custom panel

How Do Genetic Conditions Get Passed On?

Autosomal Recessive Conditions

Horizon carrier screening tests for genetic conditions that happen when both copies of a gene pair have a change. These are called recessive genetic conditions. A carrier of a recessive genetic condition is someone who has a change in one of the genes in a pair.

A couple can have a child with a recessive condition when both the female and the male parent are carriers of the same condition. With each pregnancy, this couple has a 25% (1 in 4) chance of having an affected child.

X-Linked Conditions:

These conditions are linked to the X chromosome. For X-linked genetic conditions, only the female parent needs to be a carrier to be at risk of having an affected child. A carrier female parent has a 50% (1 in 2) chance of having an affected male child or carrier female child with each pregnancy.

Benefits of Horizon Carrier Screening:

Screens for multiple genetic conditions in one test
Helps identify risks early
Supports informed decision-making
Suitable before or during pregnancy

We recommend male testing if female (pregnant woman) is a carrier.
