EP42 基因组上的‘复读机’:探秘短串联重复(STR)

from 医学遗传前沿

本期节目,聊一聊人类 DNA 中的‘复读机’, 短串联重复(short tandem repeat, STR),即 1-6bp 的连续重复序列。我们分别探讨 STR 在进化中的发生及其生物学意义、STR 的基因型检测手段、STR 扩增与疾病的关系及机制、STR 扩增相关疾病的治疗进展。希望大家在临床遇到疑难的神经肌肉疾病时,警惕 STR 的可能性,并且有机会一起探索前沿的治疗方案~相关链接串联重复在人群中的分布:10.1038/s41586-025-09886-z串联重复的毒性机制:10.1038/s41588-026-02507-z靶向DMPK串联重复临床试验:www.nejm.orgHTT base editing 治疗:10.1038/s41588-025-02172-8若对播客有任何问题或者投稿,或需要获得文字版音频总结,请联系我 [email protected]小红书/微博:@撸森森同时也可以添加微信zhaosen830进入听友交流群,谢谢Thanks♪(・ω・)ノ在小宇宙查看该单集文稿
