 * //__Fragile X syndrome-__//** Fragile X syndrome is commonly known today as the most common cause for mental retardation that is inherited from the childs parents.

__//**History-**//__ In 1943 Martin and Bell discovered that what today is called fragile X syndrome was X chromosome related. In 1969 a man named Herbert Lewis developed his own chromosomal test, but his test however was not used on a regular basis until the 1970's. Then in 1991 the FMR1 gene that causes fragile X syndrome was discovered.

Diagnosis-__//** These are the steps doctors today use to determine if someone has fragile X syndrome. 1) As the child grows the doctor keeps an eyeout for any signs of development delays, abnormal physical pheatures, and any strange behavior. 2) If any of the symptoms from step one are evident then the doctor asks the parents if there is or has been any mental retardations in their family histories. 3) If the parents say yes to step number two then the doctor will take a blood sample from the childs finger two test for the fragile X gene. This is not to be confused with telling someone that their child has fragile X for sure it is just to see if the gene exists within the person. Then there is the option of finding out if the child could have fragile X syndrome before it is born. 1)After 15-18 weeks of being pregnant it is ok for a mother to test for fragile X syndrome by having a needle inserted into the abdomen so a sample of amniotic fluid is taken. 2) Doctors take the sample to go and test it for fragile X.

 * //__Transmition-__//** Fragile X syndrome is a mutation that is inherited from a parent from one of their X chromosomes. This sex-linked mutation from the FMR1-gene is an incomplete dominant trait.


 * //__Symptoms-__//** Some physical pheature that could be hint to fragile X syndrome are large ears, a long and narrow face, large chin and forehead, flat feet (where the base of the foot has little to no arch), double-jointed fingers (where the fingers can bend foreward and backward), puffy eyes, nearsightedness or a lazy eye, and constant biting and flapping of their hands. A speech problem that might be due to FXS is when a child sspeaks in short but loud outbursts and often repeats the same thing several times. Other possible symptoms include hyperactivity, ADHD, a strong dislike of being touched, seizures, anywhere from mild to severe mental retardation, ear and/or sinus infections, hyper sensitivity to the environment, odors, light, and sound.


 * //__Treatments-__//** Unfortunatly the search for more ways to improving living with fragile X has been a long struggle. Things like speech therapy, physical therapy, and psychotherapy are some of the few things that have been proven to actually help people who have been diagnosed with FXS. Speech therapy works on teaching them to speak quieter and improve their reading and speaking ability so they can have more normal conversations with people. While one the other hand physical therapy works on helping them learn to walk properly and break bad habits.
