WebOnly individuals with >200 CGG repeats in the FMR1 gene have Fragile X syndrome. More than 99% of Fragile X syndrome cases result from expansion of the CGG repeat located in the 5'-UTR of the FMR1 gene (Monaghan et al. 2013). Large CGG repeats (>200) are generally hypermethylated which leads to transcriptional silencing of the FMR1 gene.

WebA premutation carrier is an individual, male or female, who has between 55-200 CGG repeats in the Fragile X (FMR1) gene. The full mutation is defined as over 200 CGG repeats. (A normal FMR1 gene has 6-54 CGG repeats.) Occasionally a female with a full mutation shows little or no effect of the full mutation and is sometimes referred to as a ... WebTesting of the FMR1 gene would still be needed to confirm whether or not that person has fragile X syndrome. All of this testing must be ordered by a physician or genetic counselor who can interpret the results for the patient and their family.
WebFXTAS occurs in individuals who have an FMR1 premutation and is characterized by late-onset, progressive cerebellar ataxia and intention tremor followed by cognitive impairment. Psychiatric disorders are common. Age of onset is typically between 60 and 65 years and is more common among males who are hemizygous for the premutation (40%) than ...
