Fragile X is a genetic condition. Families that carry the Fragile X gene have a number of options available to them with regards to their family planning.
The Association recommends if you or any member of your family is a carrier or fully affected by Fragile X that you inform your extended family. This gives them the option to be tested to see if they are carriers of Fragile X.
If you are a Fragile X carrier there are a number of options you might want to consider when you are planning your family.
- Becoming pregnant. If the father is the carrier of Fragile X any daughters born will also be carriers of Fragile X. A son will not be affected by Fragile X. If the mother is a carrier of Fragile X the boy or girl may be may fully affected by Fragile X, a Fragile X carrier or unaffected.
- Undergo prenatal testing. This testing is carried out before the baby is born. Prenatal diagnosis is available to any person who is a carrier of a Fragile X. Anyone considering prenatal diagnosis should meet with a genetic counsellor before becoming pregnant to order to discuss the most current prenatal techniques, their limitations and benefits.
- Preimplantation Genetic Dignosis (PGD), an IVF treatment. PGD is allows testing for the gene in undertaken before pregnancy takes place however as it is an IVF cycle it can be an invasive experience.
