首次发现GGC重复扩增在新型开放阅读框中翻译为有毒多甘氨酸蛋白,揭示其通过形成细胞聚集物导致神经元和肌肉细胞功能障碍的致病机制

📝 英文原版摘要

<p>Nature Genetics, Published online: 17 February 2026; <a href="https://www.nature.com/articles/s41588-026-02507-z">doi:10.1038/s41588-026-02507-z</a></p>GGC repeat expansions causing oculopharyngeal myopathy with or without leukoencephalopathy are located in small open reading frames and translated into polyglycine proteins that form cellular aggregates, driving neuronal and muscle cell dysfunction.
