Expansion of short tandem repeats can impair RNA and protein function and cause diseases through four main mechanisms: transcription repression, RNA gelation and sequestration of RNA-binding proteins, protein gain of function, and repeat-associated non-AUG toxic translation. Synergy between these mechanisms exacerbates disease, but also offers promising therapeutic targets.
