WebAug 1, 2006 · Abstract. Background: Fragile X syndrome (FXS), the most common cause of inherited mental impairment, is most commonly related to hyperexpansion and hypermethylation of a polymorphic CGG trinucleotide repeat in the 5′ untranslated region of the FMR1 gene. Southern blot analysis is the most commonly used method for … WebPurpose: Fragile X syndrome is associated with the expansion of CGG trinucleotide repeats and subsequent methylation of the FMR1 gene. Molecular diagnosis of fragile X currently requires Southern blot analysis to assess methylation. This study describes the evaluation of a polymerase chain reaction-only workflow for the determination of methylation status …
