Fragile X Syndrome (FXS) is a common cause of mental impairment autism. FXS is caused when the gene FMR1 shuts down and fails to produce the necessary protein for full brain function. Behavioral symptoms of FXS can include delays in speech and language development, attention deficit and hyperactivity, anxiety and unstable moods, and learning disabilities. Common physical signs include large ears, a long face, failing to reach expected height, flat feet, and loose, flexible joints. FXS is genetic, but the carrier may not have any signs of the condition.
The National Fragile X Foundation - The National Fragile X foundation unites the Fragile X community to enrich lives through educational and emotional support, promote public and professional awareness, and advance research toward improved treatments and a cure for Fragile X.
The Fragile X Research Foundation (FRAXA) - FRAXA seeks to accelerate progress toward effective treatments and ultimately cure Fragile X by funding the most promising research. FRAXA also supports families affected by Fragile X and raises awareness of this important, virtually unknown, disease.
