“研究人员以前看到的复制数量变化只是冰山一角，而其绝大部分都还未浮出水面，未被发现，”赫尔斯博士说。

"The copy number variation that researchers had seen before was simply the tip of the iceberg, while the bulk lay submerged, undetected," said Dr Hurles.

根据来自非洲、亚洲和欧洲的270个人的基因分析资料，科学家们绘制了新的“复制数量变异”图，它将改变科学家们寻找与疾病相关的遗传因子的方式。

The new CNV map – compiled from 270 individual genomes of people with African, Asian and European ancestry – will change the way in which scientists search for genes involved in disease.

It's really been a powerful tool in molecular biology because I might have a very small copy of a gene that I'm interested in and I can make enough copies that I can start to do something else with it.

这确实是分子生物学的一项利器,因为我可能只有,很少量的感兴趣的基因拷贝,而我可以马上制造出足够数量的复制品,能使我用作其他用途
