Discovering Effective Treatments & A Cure for Fragile X Syndrome

How Does FRAXA Help?

FRAXA’s mission is to find effective treatments and ultimately a cure for Fragile X syndrome. We directly fund research grants and fellowships at top universities around the world. We partner with biomedical and pharmaceutical companies, large and small, to bridge the gap between research discoveries and actual treatments.

Every member of our staff and Board of Directors is a parent of one or more children with Fragile X, making our commitment to this cause deeply personal.

Treatments for Fragile X are likely to help people affected by autism, Alzheimer’s, and other brain disorders.

What is Fragile X Syndrome?

Fragile X syndrome (FXS) is the most common inherited cause of autism and intellectual disabilities. It affects 1 in 4,000 boys and 1 in 8,000 girls worldwide.

Fragile X syndrome occurs when a single gene on the X chromosome shuts down. This gene makes a protein needed for normal brain development. In FXS it does not work properly, the protein is not made, and the brain does not develop as it should.

Symptoms of Fragile X syndrome can include developmental delays, social anxiety, and learning disabilities, which vary between individuals.
