Abstract excerpt
Fragile X-associated disorders are caused by a CGG trinucleotide repeat expansion in the 5'-untranslated region of the FMR1 gene. Expansion of the CGG trinucleotide repeats to >200 copies (that is, a full mutation) induces methylation of the FMR1 gene, with transcriptional silencing being the eventual outcome. Previous data have shown that FMR1 premutation carriers (individuals with 55-199 repeats) have increased...
