Finally, also in FXTAS, the pharmacologic inhibition of serine/arginine protein kinases (SRPKs) in flies has been able to inhibit RAN translation of CGGs but also of GGGGCC repeats (associated with c9orf72), suppressing toxicity in both disease models and also opening a novel therapeutic target in RNA toxic diseases [85]. This evidence concerns the gene C9orf72 and fragile X-associated tremor/ataxia syndrome.
