Microsatellite Expansion Diseases: Repeat Toxicity Found in Translation
Abstract
Sellier et al. (2017) show that translation of expanded CGG repeats in fragile X-associated tremor/ataxia syndrome is initiated at an upstream ACG near-cognate start codon. The resulting polyglycine-containing protein, but not repeat RNA, is pathogenic by disrupting the nuclear lamina.
