Fragile x Syndrome

A Project by Matthew Kleindolph

Basic information

Fragile x syndrome is a genetic condition that changes certain parts on the X chromosome

One in four thousand males are affected by this genetic condition and one in six thousand females are affected by fragile X


Symptoms that may occur from the disease are flexible or double joints and low muscle tone. Hyper active or impulsive behavior could show. Intellectual disability are common with the genetic condition. Long face and big ears are another common symptoms that appear from fragile x syndrome. Plus there might be some speech and language delay meaning that they could difficulty say words. Daily life is almost the same as a normal person they should have a person take them places and be with them until they can do normal things by themselves, other then that they have a normal day compared to other people. Their life expectancy is no different from other people they could live on to be one hundred.


The type of mutation for fragile x syndrome is the FMR1 gene on the X chromosome. The FMR1 provides instructions for the protein called fragile x mental retardation protein or FMRP.


There is no definitive, single treatment for fragile x. There are many things that people could do to keep them from showing symptoms of fragile x. People with fragile x should take more helpful class so that they can learn more skills. People should also take physical therapy to help them with there motor skills

Other interesting information

  1. That girls are twice as more likely to get this genetic disorder because they have two X chromosomes
  2. If a man is a carrier and he has a daughter. Then she will have the disorder and she will always be a carrier
  3. The condition that affects the boys tend to be more severe. Because boys tend to develop mental impairment and approximately one in three boys with fragile x have autism
  4. That one in six thousand boys are affected by fragile x and one in four thousand girls are affected
