Fragile x syndrome is a genetic condition that causes a range of developmental problems including learning disabilities and cognitive impairment.
Individuals with fragile x syndrome usually have delayed development of speech and language by age 2. Most males with fragile x syndrome have mild to moderate learning disability, while about one-third of affected females are learning disabled.
Children with fragile X syndrome may also have anxiety and hyperactive behavior such as fidgeting or impulsive actions. They may have attention deficit disorder (ADD), which includes an impaired ability to maintain attention and difficulty focusing on specific tasks.
About one-third of individuals with fragile x syndrome have features of autism that affect communication and social interaction. Seizures occur in about 15 percent of males and about 5 percent of females with fragile x syndrome.
