One of the biggest challenges has been the detection of CNVs.

其中最大的问题是基因克隆数变异的检测。

Even so, scientists have been able to link CNVs to a handful of complex diseases.

尽管如此，科学家们已经将CNVs和一些复杂的疾病联系起来。

Some CNVs are common, but others are rare or occur with low frequency among humans.

有些拷贝数变异是很常见的，但还有一些则在人类中极少发生或是发生的频率较低。

In 2009, I predicted that CNVs would be a hot topic in autism research (pats self on back).

FORBES: Autism And Genetics: It's Complicated

This latest research discusses CNVs that are high impact, rare number variants with pretty big effects in terms of autism risk.

These high-impact CNVs cropped up in families with several autistic individuals in the pedigree, and the authors also identified some of them in individuals from a large population of autistics.
