How possible is it that a cure will be found?

There is currently not a cure for Fragile X syndrome, even though research is being put into finding one. We do not know how close we are to finding a cure right now. Hopefully a cure will be found soon.

What are some organizations that can help a family cope with a child's disorder?

The largest organization for Fraglie X is The National Fragile X Foundation. Click the link for more information.

What limitations does the person have?

According to Parenting and Child Health Services,

• "Some boys can be affected only mildly, but some can have quite severe intellectual disabilities. Most have moderate disability. Girls usually have milder delay.


• Delays in learning, speech and communication skills, gross motor skills (such as walking and running) and fine motor skills (eg holding and using a pencil) can be a part of the developmental disability."

How can the disease be treated?

There is no proper treatment for Fragile X Syndrome although some therapy such as speech and language therapy, occupational therapy, physical therapy, and psychotherapy, can help depending upon the child's symptoms. Also, certain drugs may be used to treat behavioral problems, such as mood swings and aggressive outbursts in order to calm the child down.

What is the life expectancy of someone with the disease?

Most people who have Fragile X Syndrome are perfectly healthy in the aspect of life expectancy. Their life expectancy is no different than a normal person.

What are the physical symptoms?

The physical symptoms can differ from boy to girl and most don't tend to show until puberty.

• Male - long face, larger head, wider and longer ears



• Female - long face, large jaw, large ears, high arched palate; most females have little to none behavior or educational difficulties with Fragile X Syndrome

How is the disease diagnosed?

The disease is diagnosed through a blood test, which shows both carriers and affected individulals. This shows the exact diagnosis.

What are the chances of a person with this disease passing the disease to their offspring?

Carrier men pass the premutation to all their daughters but none of their sons. Each child of a carrier woman has a 50% chance of inheriting the gene. The Fragile X premutation can be passed silently down through generations in a family before a child is affected by the syndrome. A DNA blood test identifies both carriers and affected individuals.

How prevalent is the disease in the population?

It is unknown the exact number of occurrence of Fragile X Syndrome, but recent statistics show that it is affected in:

• 1 in 2000 boys


• 1 in 4000 girls are estimated to be affected.


• 1 in 260 women are carriers.

How does a person inherit this genetic disorder?

Fragile X is a single gene disorder carried by either a mother or a father. It is transmitted from parent to child through the genetic information (DNA) that is in the sperm and eggs.

Is it dominant or recessive?

The inheritance is different from common dominant or recessive inheritance patterns. A fragile area on the X chromosome (FMR1) has repeats in the genetic code. The more repeats, the more likely there is to be a problem. Boys and girls can both be affected, but because boys have only one X chromosome, a single fragile X is likely to affect them more severely.

Is is genetic or chromosomal?

It is transmitted from parent to child through the genetic information in the sperm and eggs.
