Fragile X syndrome is the leading cause of inherited intellectual disability for any individual. The chances you can pass on Fragile X to your baby doesn't change with advancing age, unlike passing on Trisomy 21 or Down's Syndrome, which becomes more common as the age of the pregnant mom increases. Most pregnant women do get screened and or at least ask about Down syndrome, which is NOT inherited, it just happens
- Pregnant women under the age of 40 have a higher risk to be a Fragile X mutation carrier than a chance to have a child with Down syndrome
The test is a non-invasive blood test, it can be done at NxGen MDx and can be done during pregnancy or during a pregnancy planning visit, which we recommend at Women's Health Practice.
