Does PGD test for Fragile X?

The PGD analysis for Fragile X is done by a process called linkage—the lab uses genetic markers very close to the gene to distinguish the mother’s two different X chromosomes.

What are the chances of passing fragile X syndrome?

Fragile X Syndrome is a Common Rare Disease About 1 in 259 women carry Fragile X and could pass it to their children. About 1 in 800 men carry Fragile X; their daughters will also be carriers.

Can IVF prevent fragile X syndrome?

If you are currently trying to have a child and are having infertility problems, premature menopause could be a cause. In addition, some of the options for reducing your risk of having another child with fragile X syndrome, such as IVF with PGD, may be a less viable option due to premature menopause.

What is the prognosis for fragile X syndrome?

Life expectancy for people with fragile X syndrome is generally normal. Many affected people participate in an active lifestyle and have good health. Some people are more prone to a number of medical problems, such as ear infections and/or seizures .

Can a fragile X embryo be screened for PGD?

Embryos produced from couples who are Fragile X carriers may have varying numbers of CGG repeats. Therefore, identification of those embryos without a large number of CGG can reduce the likelihood of Fragile X associated problems. A number of PGD techniques have been described to screen embryos for PGD. These are difficult cases.

Why does the success rate increase after PGD?

This also decreases the chance of multiple birth and the chance of prematurity. It also allows for the cryopreservation of extra “normal” embryos for future pregnancies. Our experience has shown that even when far fewer embryos are returned to the uterus, pregnancy success increases following PGD.

Can you get PGD after a failed IVF cycle?

The good news is that PGD is now available at the Fertility Institutes for couples who have been met with failure in a prior IVF cycle or cycles. Single cycle IVF success rates (the chance of becoming pregnant) in our program can be raised significantly when 2 or 3 embryos known to be chromosomally normal are transferred.

Why are children with Fragile X syndrome more unstable?

Individuals who have the Fragile X premutation have a higher risk of having children with a larger number of repeats. This is because the larger the number of CGG repeats, the more unstable the FMR1 gene becomes. Thus, there can be a family with no history of Fragile X syndrome in which it suddenly appears in a number of offspring.
