Abstrakt: Fragile X syndrome is caused by expansion and subsequent methylation of a CGG trinucleotide repeat in the FMR15′-untranslated region. Southern blot analysis is typically required to determine expansion size for triplet repeat lengths >200. We describe a triplet-primed polymerase chain reaction-based method using automated capillary electrophoresis detection for qualitative assessment of expanded CGG repeats.
