Abstract excerpt
The Fragile X syndrome is caused by a CGG repeat expansion >200 in the promoter of the Fragile X mental retardation 1 (FMR1) gene termed full mutation (FM). These alleles are silenced through methylation of the FMR1 promoter, leading to deficit of the FMR1 protein (FMRP), and neurodevelopmental changes. However, occasional FM individuals have a complete lack of methylation, and those typically have only minor...
