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. Webgenetic cause of autism. The diagnosis is made with a genetic test that determines the number of CGG repeats in the fragile X gene, FMR1. FMR1 variant testing has been …
