FMR1 premutation alleles uniquely produce FMR1 transcripts with an elongated CGG repeat, leading to the hypothesis that premutant transcripts cause the neurodegenerative disease in carriers.Recently Jin et al. demonstrated, in Drosophila, that FMR1 premutation RNA causes neurodegeneration.

As shown by molecular cloning of the fragile X locus, Fragile X mutations are unstable expansions of a CGG trinucleotide repeat, located in the first exon (non-protein-coding) of the FMR1 gene (for Fragile X Mental Retardation).
