Abstract excerpt
Fragile X syndrome (FXS) is caused by the expansion of a CGG repeat in the 5'UTR of the FMR1 gene and the subsequent methylation of all CpG sites in the promoter region. We recently identified, in unrelated FXS families, two rare males with an unmethylated full mutation, that is, with an expanded CGG repeat (>200 triplets) lacking the typical CpG methylation in the FMR1 promoter. These individuals are not...
