📝 英文原版摘要
<p>Nature Genetics, Published online: 18 February 2026; <a href="https://www.nature.com/articles/s41588-026-02517-x">doi:10.1038/s41588-026-02517-x</a></p>Oculopharyngodistal myopathy and oculopharyngeal myopathy with leukoencephalopathy are diseases caused by 50–200 repeats of the GGC DNA motif located in diverse sequences annotated as non-coding. This work shows that these repeats are embedded in previously unrecognized open reading frames, leading to their translation into novel and toxic polyglycine proteins.
