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.
Three disorders which are sex-linked are: Fragile X syndrome Duchenne muscular dystrophy Colour blindness (most forms, but not all)
Klinefelter Syndrome is sex-linked, because it is a genetic defect that results in a male having an extra X chromosome.

No, fragile x syndrome is not progressive
Martin Bell discovered Fragile X syndrome in 1969 when he observed a family with multiple members exhibiting intellectual disabilities and behavioral issues. He noted a specific physical characteristic, an abnormality on the X chromosome, which he termed "Fragile X." This discovery laid the groundwork for further research that eventually identified the genetic mutation responsible for the syndrome. Subsequent studies confirmed that Fragile X syndrome is linked to the expansion of a repeat sequence in the FMR1 gene on the X chromosome.
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.
Males and females can be carriers, male carriers can only pass on to their daughters, they will be carriers as well have a premutation. Females can pass on to their sons or daughters, they will have the premutation or the full mutation.
Yes, Fragile X syndrome is an X-linked genetic disorder that causes a range of developmental problems. It is caused by a mutation in the FMR1 gene located on the X chromosome. The condition is more commonly seen in males than in females because they have only one X chromosome.
