Fragile x chromosome is the most common inherited cause of mental retardation. The disorder fragile x syndrome is a mutation of the FMR1 gene on the X chromosome. This disorder occurs more in males than another X chromosome because males only have one X-chromosome and if the disorder is on that X chromosome, then there would be no way it would cover it up. In females, since they have two X chromosomes, the symptoms wouldn’t be as severe because only one X chromosome has the disorder and since females have 2, then the other X chromosome could cover up the diseased one. Some symptoms of fragile x syndrome are intellectual disability, elongated face, large or protruding ears, flat feet, large testicles and low muscle tone. Also hand flapping, atypical social development, shyness and limited eye contact can occur. These symptoms would be more severe in males than females. At this time there is no cure for this but there is optional therapy for speech and language. Medications can be helpful for aggression, anxiety, hyperactivity and poor attention span. I think that since this syndrome is a very common one, it will be hard to control and stop because it comes in many different forms.
