Fragile X syndrome is caused by a mutation that prevents the Fragile X mental retardation (Fmr-1) gene from being transcribed. This gene is located on the X chromosome (the sex chromosome). Since males only carry one of these chromosomes, they are twice as likely to be affected by the mutation than females.

What cause fragile X syndrome?
The fragile X syndrome is a genetic disorder caused by mutation of the FMR1 gene on the X chromosome.
Why are males more likely to have fragile X syndrome?
males have only one copy of the X chromosome. Males who inherit the full mutation are expected to have mental impairment. A female's normal X chromosome may compensate for her chromosome with the fragile X gene mutation
Fragile X syndrome affects only females?
No, Fragile X is on the X chromosome. Females have 2 X chromosomes and Males have an X and a Y Chromosome. Therefore, both males and females can have Fragile X (they can have the full mutation or be carriers). Males are usually more severly affected because they have only one X Chromosome.
What is an example of a genetic disorder that is caused by insertion of extra codons in the X sex chromosome?

What is an example of a genetic disorder that is caused by insertion of extra codons in x sex chromosome?
Fragile X Syndrome
Is fragile x syndrome sex linked?
Yes. It is found as a mutation on the X chromosome (a sex chromosome) so it is sex linked. The gene for Fragile X is carried on the X chromosome. Because both males (XY) and females (XX) have at least one X chromosome, both can pass on the mutated gene to their children.
Is fragile X syndrome related to klinefelster?
No, Klinefelter is due to an extra chromosome, Fragile X is due to the FMR1 gene being turned off and producing no FMR1 protein
Where on the X chromosome does Fragile X take place?
Fragile X is a result of a mutation in the FMR1 gene on the X chromosome.
What are four traits that are transmitted on the x chromosome?
The X chromosome carries traits that determine characteristics and conditions that may be passed down to the offspring. Some conditions carried on the X chromosome are hemophilia, Duchenne muscular dystrophy, fragile-x syndrome and red-green color blindness.
