Carrier Testing home

What about future pregnancies?It is important to remember that you and your partner have both been shown to be carriers of an abnormal SMA gene. This means that in each pregnancy the two of you have together, that baby will also have a 1-in-4 (25%) chance of having SMA. If you want to know whether or not that baby will develop SMA, you need to have amniocentesis or CVS in each pregnancy.
There are several choices couples in your situation can make when thinking about possible future pregnancies. Some couples decide to:
- Have prenatal testing, such as amniocentesis or CVS
- Accept this level of risk and have other children
- Go through in vitro fertilization and test the embryos using Preimplantation enetic Diagnosis (PGD)
- Adopt
- Use donor sperm or donor eggs
- Not have other children
