Large-scale copy number variants (CNVs) detected in different ethnic human populations.
The large-scale copy-number variations (CNVs) in the human genome are associated with developmental disorders and susceptibility to diseases. More importantly, CNVs may represent a major genetic component of our phenotypic diversity. Following the development of methodologies and introduction of new research platforms, accumulation of the nature and pattern of CNVs from normal populations has progressed. The examination of relatively large numbers of specific ethnic groups has recently started. Although the results are not always consistent, it is likely that different human populations bear different CNVs, as is the case for single-nucleotide polymorphisms (SNPs) and insertion-deletion (indel) polymorphisms. We review recent publications about the nature of inter-population, especially inter-ethnic group, differences of CNVs.
