Fragile X Syndrome
Fragile X Syndrome is a chromosome abnormality that is inherited. It is the most common inherited cause of mental impairment. Fragile X Syndrome is more common in boys occurring 1 in 3,600 while 1 in 4,000 to 6,000 girls. Approximately 35% of children with Fragile X have Autism as well.
It is believed that between 2 and 6 percent of all children with Autism have the Fragile X gene mutation. DNA blood tests can be taken to see if Fragile X exists in an individual.
Fragile X Syndrome has similarities to Autism symptoms such as: hand flapping, poor eye contact and short attention span. Physical characteristics include: long faces, prominent ears and a larger head circumference. Females will show some of these features however; these characteristics are more common in males.
Fragile X Syndrome behavior differs in males and females as well. Girls tend to be shy and they have problems with social interaction. Depression can occur as well.
Boys tend to be easily distracted and have impulsive reactions to situations. As in Autism, there are similarities in sensory areas such as: sensitivity to clothing, light and objects. Girls and boys both can show anxiety in situations where their routine is broken.
Fragile X children are very loving with a wonderful sense of humor and generally like to be around people. Autism and Fragile X are often associated with one another due to their many similar characteristics and resulting behavior.
It is important to note that no two children with Autism or Fragile X Syndrome will be alike. If you have any concerns whether your child may have Fragile X, please see your doctor and ask him to request a DNA blood test.
