EP6 拷贝数变异,古老而神秘@段睿智

from 医学遗传前沿

我们早在DNA被发现为遗传物质之前就已经发现了拷贝数变异的存在,但是直到今天,拷贝数变异的形成机制、人群分布和疾病关联依然有太多未解之谜。本期节目,我们请到了来自美国贝勒医学院的段睿智博士,聊一聊我们认识拷贝数变异历史进程,尤其是James Lupski实验室对拷贝数变异研究的贡献,以及转座子相关拷贝数变异形成机制的前沿研究。同时我们也简单介绍了临床中拷贝数变异的检测指征和检测方法。和EP2的嘉宾浩炜一样,睿智也即将进入WashingtonUniversity in St. Louis的Clinical Laboratory Genetics and Genomics Fellowship (LGG) 培训项目,成为一名遗传检验科大夫,他也在节目的最后对该项目的申请经验进行了分享。主要内容03:47 James Lupski实验室对拷贝数变异研究的贡献10:30 拷贝数变异的复杂形成机制研究14:10 转座子alu元件导致拷贝数变异的前沿研究19:35 临床拷贝数变异的检测指征22:00 临床拷贝数变异的检测方法27:42 LGG项目申请经验相关链接Luspki实验室在CNV方面的代表工作:https://www.nature.com/articles/ng.2768https://www.nature.com/articles/nrg.2015.25刘鹏飞教授在关于复杂拷贝数变异成型机制的cell paper: https://www.sciencedirect.com/science/article/pii/S0092867417301277本月发表的很有意思的一篇Alu导致人类“失去”尾巴的nature paper:https://www.nature.com/articles/s41586-024-07095-8在小宇宙查看该单集文稿
