In brief: Maybe before

If both parents are identified as carriers, prenatal genetic testing can be done.
Chorionic villus sampling (cvs) is the most common form and can be done between 10 and 14 weeks of gestation. Amniocentesis can be performed around 15 weeks. Testing can even be done before implantation. With canavans, genetic counseling and genetic testing can be done for families with two parental carriers.
