Diseases associated with FMR1 include … 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.
