Feature Quiz: Fragile X Syndrome (FXS) - Alt Text Version
What are some symptoms of FXS?
Answer: Symptoms that a child might have FXS include:
- Not sitting, walking, or talking at the same time as other children the same age
- Trouble learning new skills
- Difficulty in school
- Avoiding eye contact
- Trouble paying attention
- Hand flapping
- Acting and speaking without thinking
- Being sensitive to sights and sounds
- Being very active
- Aggressive behavior
Who is usually the first person to notice symptoms of FXS in a child?
Answer: Parents are usually the first to notice symptoms of FXS at about 12 months of age for boys and at about 16 months of age for girls.
Is FXS the same as autism spectrum disorder (ASD)?
Answer: No. FXS is a specific inherited condition that can be diagnosed by a laboratory test. Autism spectrum disorder (ASD) is a pattern of broadly defined behaviors, and doctors look at a person’s behavior and development to make a diagnosis. There is no laboratory test to diagnose ASD. Not all children with FXS have ASD; however those with FXS are more likely to have ASD than those without FXS.
What types of services do children with FXS need?
Answer: Every child with FXS will have different abilities and challenges. Services might include:
- Speech therapy, occupational therapy, and other therapies to learn to talk, walk, and interact with others.
- Medicine to help with behavior problems.
For the best treatment plan, people with FXS, parents, and health care providers should work closely with everyone involved in treatment and support. Include teachers, childcare providers, coaches, therapists, and other family members in this process.
Can you “catch” FXS from someone who has it?
Answer: No, you cannot “catch” FXS from someone who has it. FXS is inherited. It is caused by a big change in a single gene that is passed down from a mother who is a carrier. A carrier has a smaller change in that gene, but does not have FXS. Most of the people who are carriers do not know it.
