copy number variation

基本解释

Recently geneticists have taken a closer look at a genetic aberration previously considered rare: copy number variation (CNV).
最近遗传学家对以前被认为很罕见的遗传变异：拷贝数变异（copy number variation ，CNV）进行了更细致的研究。
DEFB gene products are small antimicrobial proinflammatory peptides, and copy number variation (CNV) could reasonably influence susceptibility to infection and inflammation.
DEFB基因产物是小分子抗菌肽，且拷贝数变化（CNV）可显著影响易感性及炎症反应。
The copy number of TYLCV in tomato materials with Ty-1/ Ty-3 and susceptible tomato materials showed a similar trend of variation.
精确控温种植的含Ty-1/Ty-3的近等基因系番茄材料中病毒的含量变化趋势与此相同。

For example, a recent (2007) study by Sebat et al. found a clear link between ASD and de novo copy number variation (de novo mutations are those that arise for the first time in the children).

拷贝数变异
Background and objective Loss of heterozygosity (LOH) and Copy number copy number variation (CNV) of DNA sequences is a common feature of cancer genomes, which is thought to be linked to tumorigenesis and progression.
背景和目的DNA序列的杂合性缺失(LOH)和拷贝数变异(CNV)普遍存在于肿瘤基因组,并认为与肿瘤发生发展相关。
拷贝数多态

拷贝数变异
Finally a newly defined genetic variation, copy number variation, was briefly introduced. This paper also summarized the shortcomings of current genome-wide asso-ciation studies and perspectives of its future.
最后介绍了人类基因组拷贝数变异的研究进展,总结了人类全基因组关联研究所取得成就和存在的问题,并对全基因组关联研究未来的研究重点和要解决的问题进行了展望。
