What is the first treatment tried for genetic risk in related couples?

Related partners may share gene variants inherited from a common ancestor. Carrier screening uses a blood or saliva sample to look for selected recessive conditions. A person can carry a variant without having the condition; the result becomes more useful when both partners are tested and interpreted together.

A positive carrier result does not diagnose illness in either partner. It identifies a possibility that may affect children, so a genetics professional can explain inheritance and whether broader testing is appropriate.

Arrange a preconception appointment and share your family history, previous pregnancy history, and known diagnoses in relatives. Ask whether a targeted panel or broader screening fits your backgrounds. [Genetic Carrier Screening](/treatments/diagnostics-and-imaging/genetic-carrier-screening/) and [Pre-marital Screening](/treatments/diagnostics-and-imaging/pre-marital-screening/) may be discussed before pregnancy.

If both partners carry a variant for the same condition, options can include diagnostic testing during pregnancy or assisted reproduction with embryo testing such as [PGT-M](/treatments/fertility-and-assisted-reproduction/pgt-m/).

Seek genetics or obstetric advice before trying to conceive when you know of an inherited condition, repeated unexplained pregnancy loss, a child with a genetic diagnosis, or close biological relatedness between partners. If pregnancy has already begun, contact your maternity team promptly because the timing of available tests can matter.

Which conditions should we screen for given our family backgrounds? If one result is positive, should the other partner have follow-up testing? What choices would be available before or during pregnancy?
