Validation of a Commercially Available Screening Tool for the Rapid Identification of CGG Trinucleotide Repeat Expansions in

Recently developed PCR-based methods for fragile X syndrome testing are often regarded as screening tools because of a reduced reliance on Southern blot analysis. However, existing PCR methods rely essentially on capillary electrophoresis for the analysis of amplicons. These methods not only require an expensive capillary electrophoresis instrument but also involve post-PCR processing steps. Here, we evaluated a commercially available PCR-based assay that uses melt curve analysis as a screening tool for the rapid detection of CGG repeat expansions in the fragile X mental retardation 1 (FMR1) gene.
