Translation of an uORF containing GGC repeat expansions into toxic polyG protein is reminiscent of another neurodegenerative disorder, Fragile X-associated tremor/ataxia syndrome (FXTAS), caused by expansions of 80-200 CGG repeats in the 5′-UTR of FMR1, reviewed in Zhou et al.20. Here, FMR1 is linked to fragile X-associated tremor/ataxia syndrome.
