来自主题: Biology版 - 请教neurogenomics职业规划
你说的common SNP估计是GWAS的结果吧。
我才入行一年,正好碰到sequencing这个潮流,所以直接关注的都是rare mutation;
对于complex disease,基本上现在exome seq做的多的就是rare/de novo SNP,认为他
们有large effect size,可以解释autism这样幼儿疾病;这点我个人是很相信的。但
过去的GWAS所有的common SNP就都没意义吗?我觉得有些common SNP对于疾病的
susceptibility还是有贡献的,只不过是small effect size。。。所以我觉得如果有
足够多的样本,每个样本都有序列(目前当然不可能),完全可以做个sequencing-
based的association study。
其实我倒巴不得测序成本降低的慢点,这样做我们这行的就不会太吃力,有更多的时间
来“忽悠”。比如现在你要再起步做exome sequencing就都已经晚了,因为做的人已经
太多太多了。
但其实我个人觉得测序成本降低的很快,所以很快就可以做很多的whole genome

de novo SNP 是啥?既然叫做polymorphism,那人群里起码1%,de novo怎么可能有这
么高的频率
你说SNP有small effect,理论上当然可能性是存在,但是我刚说了,起码目前做了这
么多GWAS,重复性就是非常差,绝大部分在功能上也没能解释,这个是目前的事实
至于将来的发展,还是我前面说过的,没人能预料,最安全的搞法,只能不把自己钉死
,啥热就搞啥,还有就是和医生联系起来,最好自己能拿到标本。只能仰人鼻息
至于copy number,现在做的工作还是相当少的,远远不如GWAS那种水平,你不要急于
下结论。做法的话,如果你先想到的是NGS,显然你还相当不了解这个领域,这也从另
一个角度说明了这个领域还是比较有东西可挖的。用CMA或者SNP array都可以call
copy number variation,而且比NGS便宜太多了,分辨率也不是什么10M,现在几百K可
以说很容易call出来,几十K也是常有的事。当然,现在主要还是针对基因区域。我在
clinical lab,CMA发现基因缺失或者gain并能够解释病因的比例不能说低,加上便宜

最近 对这个领域 稍微研究了一下,懂得不多,只是提提个人观点
其实你们两个人 说的是对的
你可能看过RP Lifton的papers。他一直致力于 研究 rare mendelian diseases。 他
目前和BCM,Wash U@SL 和 JHU 一起在做 mendelian genetics consortium。 通过在
全世界找 “extreme phenotype - disease outliers” 和 “inbred family的疾病”
来寻找 human knockout的phenotype。
通过 RP Lifton的实验,你发现,这个世界上 仍然有很多 monogenic的病。 但是从
临床的角度来考虑, 研究 monogenic的疾病 究竟有治疗价值吗? 1/100,000 的
mutation导致的 rare disease, 有哪个药厂会愿意生产药物来治疗呢? 所以,工业圈
自然也不会对这个领域感兴趣...
但是,你如果仔细听听RP lifton的讲座,你会发现 “发现rare disease其实并不是RP
lifton的目的”!! 通过 研究 ext... 阅读全帖
