About Fragile X Syndrome. Fragile X syndrome is a genetic disorder that affects a person’s development, especially that person’s behavior and ability to learn. In addition, Fragile X can affect: Communication skills. Physical appearance. Sensitivity to noise, light, or other sensory information. Fragile X syndrome is the most common form of ...
Aug 5, 2021 · Some children with Fragile X begin talking later than typically developing children. Most will talk eventually, but a few might stay nonverbal throughout their lives. Sensory. Many children with Fragile X are bothered by certain sensations, such as bright light, loud noises, or the way certain clothing feels on their bodies.
Aug 5, 2021 · The genetic disorder Fragile X syndrome, which results from mutations in a gene on the X chromosome, is the most commonly inherited form of developmental and intellectual disability.

Apr 25, 2022 · Fragile X results from a change or mutation in the Fragile X Messenger Ribonucleoprotein 1 (FMR1) gene, which is found on the X chromosome. The gene normally makes a protein, called FMRP, that is important for creating and maintaining connections between cells in the brain and nervous system.
Apr 25, 2022 · FXTAS is a late-onset condition (occurs in people older than age 50) that develops in some men and women with an altered form of the Fragile X gene. Those with FXTAS do not have the intellectual or developmental disabilities common in Fragile X syndrome.
May 7, 2012 · Recent research supported by NICHD has demonstrated how the protein missing in Fragile X syndrome acts as a molecular "toggle switch" in brain cells. 7 In Fragile X syndrome, a genetic mutation removes the FMRP from cells, interfering with protein production and signaling at the synapses (the junctions between brain cells where chemical communication occurs). This leads to structural changes ...
Aug 5, 2021 · The majority of Fragile X research supported by NICHD is funded through the IDDB. The IDD Branch’s three Fragile X Syndrome Research Centers are geared toward stimulating multidisciplinary, multi-institutional research and translating basic research findings into clinical practice.

What are the symptoms of Fragile X-Associated Tremor and Ataxia Syndrome (FXTAS)? En Español Although FXTAS affects individuals differently, the symptoms of the disorder are similar to those of Parkinson's or Alzheimer's disease, including memory loss, slowed speech, tremors, and a shuffling gait. 1 Some people will have many symptoms that appear quickly and get worse over time.
A healthcare provider can perform developmental screening to determine the nature of delays in a child. If a healthcare provider suspects the child has Fragile X syndrome, he/she can refer parents to a clinical geneticist, who can perform a genetic test for Fragile X syndrome. 2
Aug 19, 2021 · More recently, researchers have identified two disorders—FXPOI and Fragile X-associated tremor/ataxia syndrome—that also are associated with changes in the FMR1 gene, but that have features and symptoms vastly different from FXS. Women with FXPOI often experience irregular menstrual periods, early infertility, and premature menopause.
